Automatic naming can be skipped in only two cases: when splitting by bookmarks or if output file name is directly specified for each output document when splitting by manual page ranges. Double click on document title in “Define Output Documents and Page Ranges” view to specify a custom document name. You can also specify custom document properties such as document's "Title", "Author", "Subject" and "Keywords". If no custom properties are specified, then these values will be copied from input document.

Turn on "Create Folders" option to generate disk folders that mirror bookmark tree structure of the input document (more details). This option is only available when splitting by bookmarks.

IMPORTANT: When splitting a document using bookmark tree, documents are named after corresponding bookmark titles (more details).

3. 4. Security Settings

You can limit access to an Adobe PDF document by setting passwords and restricting certain features such as printing and editing. When a document has restricted features, any tools and menu items related to those features are dimmed.

"Password protect output documents": Check this option to restrict access to output files or password protect document permissions. If document password is specified, then users will be prompted to enter password every time they will try to open output document. Leave document password blank if you do not want restrict access to the document. If permissions password is set, then others will not be able to change document editing and printing permissions unless they enter this password. If you are also restricting printing or editing you should also add a password to enhance security. Please note that some third party PDF reading software might not support these security settings.

You can set the following document access permissions:

• "Allow document editing": Check this option to allow others to edit output documents.
• "Allow document printing": Check this option to allow others to print output documents.
• "Allow copying to clipboard": Check this option to allow others to copy selected text or images to the clipboard.
• "Allow editing of text notes": Check this option to allow others to edit text notes in output documents.

3. 5. Configuring Splitting Modes

3. 5. 1.Configuring "Equal size documents of N Pages" mode

The only available option for this splitting method is number of pages per document. Specify any number greater than 0. Input document will be split into multiple output documents N pages each. Last document might have less pages than others, if number of pages in the input is not divisible by N.
Number of documents created = (Number of Pages In Input Document + (N-1)) / (N)
"Define Output Documents and Page Ranges " section of the settings dialog is not available in this mode.

3. 5. 2. Configuring "Use Bookmark Tree" mode

This method is available only if input document has bookmarks defined. It creates number of output documents: one per every bookmark. User can control the level of bookmarks used in the splitting process by specifying starting and ending levels (top most bookmark level is 1). For example, if you want to create documents that will contain pages defined by top level of bookmark hierarchy (one document per bookmark section) specify levels from "1 to 1".

"Define Output documents and Page Ranges" section of the settings dialog is not available in this mode.
"Output naming and destination" section of the settings dialog is not fully available in this mode. User can only select output folder, but can't control naming of the documents. Output documents are named using bookmark titles. White spaces are replaced with underline symbol. For example, if input document has 3 top level bookmarks: "Documentation Roadmap", "API Changes", "Index of Methods", than 3 output documents will be created (assuming user selected bookmark levels from "1 to 1" for splitting) with the names: DOCUMENTATION_ROADMAP.PDF, API_CHANGES.PDF and INDEX_OF_METHODS.PDF.

3. 5. 3 Configuring "Use Separator" mode

This method is available in AutoSplit Pro plug-in only. The idea behind this method is to define special "separator" pages that designate locations in the document where it needs to be splitted. For example, inserting a blank page is a very popular way of separating continuous groups of pages in the PDF document. There are three different separator types available in this mode:

• Page with matching text
• Blank page
• Blank image page

3. 5. 3. 1. Splitting by page with matching text

Input document is scanned for pages that contain specified text (or regular expression pattern). Typically, this text should occur on the first page of the group of pages that should be extracted into separate document. Document is split into multiple files at those locations. Pages that contain matching text become first pages in the corresponding output documents. Click on the small button ("…") that is located to the right of the "Use separator" menu to open "Separator Page By Text Search" dialog where you can specify text to search for along with text matching options.
            For example, input document contains multiple reports of variable length, between 1 to 5 pages each. The goal is to split it into multiple files with one report per document. We know that first page of each report contains a text string of the following format: "Report 2345", "Report 1123" and so on. The word "Report" is followed by exactly 4 digits. This can be accomplished by specifying separator page with matching text: "Report  \d{4}". Make sure that "Use regular expressions" option is turned on. This regular expression pattern will only match text that contains the word "Report" with 4 digits after it.

3. 5. 3. 2. Splitting at blank pages

"Blank page" option: input document is expected to have pages with content separated by completely blank PDF pages. Blank pages should not have any elements: either visible or hidden. New output document will be created for every continuous page range between blank pages. Blank pages will be discarded and will not be included into any output documents.

3. 5. 3. 3. Splitting at blank image pages

PDF documents can be created from the output from fax or a scanner. In this case, PDF document contains no other elements, but single image of every page. This image represents a page in the original document. Blank pages can be easily inserted into such documents by scanning a blank page. Split by blank image page can automatically detect such pages and split input document at those location. Software provides a way to adjust for amount of noise that is contained in the scanned image of the blank page. Click on small button ("…") located to the right of "Use separator" menu to open "Blank Image Page Settings" dialog. Move slider to adjust sensitivity of the algorithm or select a sample page that represents the worst case of a blank page (most noise, black edges and etc.).. Remember that adjusting this parameter too high or too low may result in misclassification of blank pages and missing a valid splitting boundary.

3. 5. 4. Configuring "Use Manually Defined Page Ranges" mode

3. 5. 4. 1. Defining Pages Ranges

In this method user can specify exactly how many output documents need to be created and what pages have go to which output document. Every output document is described with a set of page ranges that it suppose to contain. Each page range can have additional options such as odd/even pages selection, reversing page order or adding a watermark to each page. Page ranges can be defined either by specifying starting and ending page numbers or by starting page number and number of pages in the range. Page ranges can be also created automatically from individual bookmark.

• To create new output document definition: click "Add Output Document" button in the "Define Output Documents And Page Ranges" section. "Specify Page Ranges" dialog would appear on the screen. Specify desired individual page numbers and page ranges that should be extracted into the new document. You can enter all page numbers as a comma-separated list, e.g., 1, 4-8, 10-20. Swap first and last page number of the page range to specify that these pages need to be processed in reverse order, e.g., 5-1. You can also specify that only even or odd pages should be processed from a specified page range. Add letter 'E' at the end of the page range to indicate only even pages, e.g., 1-5E, or add letter 'D' to indicate only odd pages, e.g., 1-5D. Click "OK" button once you have entered all necessary page numbers. The new document entry will be created in the output document list with a name "Document N" (where N is an integer number starting from 1, for example "Document 1"). This name has nothing to do with actual output document name and merely serves as document design name. This new entry is getting automatically selected in the view and several more buttons become active allowing user to add individual page range definitions to this output document. Double click on the document name to open "Output Document Options" dialog if you want to enter a specific filename for the output document.
• Right click on the document name to active a document menu that contains variety of operations you can perform on the output document entry.
• To delete a document from design view: select document in the list and click "Remove Document" button.
• To delete all documents from design view: click "Remove All Documents" buttons. All document definitions will be removed and design view will be cleared. No documents will be defined for the output.
• To manually add a page range to the output document: select desired document in the list and click "Add Range …" button. "Range of Pages " dialog will appear on the screen. Specify starting/ending page numbers or starting page and number of pages. User can also retrieve page numbers from bookmarks (if there are any bookmarks defined for input document). Click "From Bookmark" buttons to assign page number from a bookmark. There are 4 additional options that user can define for each individual page range: "Include Even Pages From The Range", "Include Odd Pages From The Range", "Reverse Page Order In The Output Document" and "Add Watermark To Every Page In Output".
• Transparency level of a watermark can be adjusted between 0 and 100%. Watermark can be placed either in front or behind the page content. Placing a watermark behind page content sometimes might produce unexpected results. Some documents may contain page elements that are indistinguishable from white page background, but can obscure watermark visibility. Use “View / Navigation Tabs / Content “ tool to inspect actual page content before deciding on placing watermarks behind a text content.
• To quickly add a page range from the bookmark: select desired document in the list and click "Range From Bookmark..." button. "Select Bookmark To Define Page Range" dialog will appear on the screen. Select a bookmark from the tree view and click "OK" button.
• To edit existing page range definition: select a page range in the list and press "Edit Page Range …" button. You can also double click on the page range entry in the list and "Edit " dialog will pop up on the screen.

3. 5. 4. 2. Splitting by Text

To define pages from document text: select a desired output document in the list and click "Pages From Text…" button. The "Extract Pages By Text Search" dialog will appear on the screen. The dialog provides three options for defining what should be the output of the operation: single page, set of all matching pages or a page range. Single query is added to the list of page ranges as a result of this operation. This query would be executed at the run time and result of the text matching operation would be added to the output document. It's possible that query could not yield any matching pages. Only one matching pattern needs to be specified for finding single page or set of all matching pages in the document. If you want to define a page range, separate matching patterns needs to be specified for starting and ending pages. When executing such query, plug-in tries to find a page in the document that matches first page pattern. After this page is found, plug-in will search for the page that matches last page pattern. This process will be repeated resulting in one or more page ranges depending on the document content. In many cases, it's hard to come up with matching pattern that defines the last page of the range. For example, chapters in the book do not have any special keywords or text patterns that designate the end. The solution is to define the same matching pattern for the last page as for the first page and check "Exclude last page from the output page range" checkbox.
For more information on how to use this functionality see "Split by Content: extracting pages using keywords and text patterns" section.

3. 5. 4. 3. Splitting by Element Content

To define pages by element content: select a desired output document in the list and click "Pages From Content…" button. The "Extract Pages By Element Content" dialog will appear on the screen. The dialog provides 18 different options that can be selected to identify pages that need to be extracted. Page is included into the output document only if it contains ALL specified elements or attributes. Available options are:

• "Image" – page contains embedded image element.
• "Form elements" – page contains form or any interactive elements such as push buttons, check and radio buttons, text entries and etc.
• "Postscript object" – page contains embedded postscript data.
• "Shading" – page contains shading element.
• "Transparency" – page contains transparency effects (any PDF element that has transparency such as highlighting or watermark).
• "Page is rotated" – page orientation is different from vertical: it is rotated 90, 180 or 270 degrees.
• "Page transition" – page has an associated page transition effect.
• "Submit form action" – page contains an element that has "Submit Form" action associated with it.
• "Reset form action" – page contains an element that has "Reset Form" action associated with.
• "Link to a page in the same document" – page has a link to another page in the same document.
• "Link to a page in another document" – page has a link to a page that is located in another PDF document.
• "Link to an internet address (URI)" – page has a link to a resource that has web/internet address.
• "Text comment (annotation)" – page contains text box comment or any other element containing text annotation element.
• "Note comment (popup)" – page contains a popup note comment that can be either hidden or visible.
• "Launches an application or prints" – page contains an element that launches another program, opens PDF documents or performs printing.
• "Executes JavaScript code" – page contains an element that has associated action that executes JavaScript code.
• "Highlighting" – page contains highlighting elements (bright transparent markings created with "Highlight" tool).
• "Rubber stamp" – page contains rubber stamp annotation element.

3. 5. 4. 4. Email Output Documents

You can email output documents created in "Use manually defined page ranges" splitting mode. This splitting mode is the only mode that defines an exact number of output documents as well as their page content. The software allows user to specify a different email recipient for each output document. Email options such as recipients, message subject and text are specified on per document basis. Double-click on a document name in the output document list and select "Email Options" tab in the "Document Properties" dialog. Check "Send this document via email" if you want to send this document via email. Enter email addresses into "To", "CC" ("carbon copy") and "BBC" (blind carbon copy") fields. Type in email subject and message text. The document itself will be emailed as binary file attachment. Check "Show email confirmation dialog before sending each file" option if you want to verify or edit each outgoing email message in your default email application. Depending on the operation system, user account type and account security settings, you may be prompted by Windows to confirm each outgoing message. The Windows security dialog typically has an option to stop asking for confirmation. Please note that this option only works until your restart Windows. This is a security feature that is build into Windows operating system and cannot be easily disabled. All email messages will be sent via your default email application (such as MS Outlook, MS Outlook Express, Thunderbird and etc.). It requires that your email client should be configured to support MAPI protocol (most email clients do support MAPI by default and most likely no action is required to turn it on). MAPI (Messaging Application Programming Interface) is an application programming interface (API) designed by Microsoft. Any software that supports MAPI can communicate with any mailserver and send and receive data via this interface regardless of their type and software provider.

3. 6. Split by Text: extracting pages using keywords and text patterns

Splitting document based on actual text content is a very powerful feature of the plug-in. In order to get most out of it sometimes it's necessary to use regular expressions to define matching text patterns. A regular expression is a pattern that is matched against a subject string from left to right. Most characters stand for themselves in a pattern, and match the corresponding characters in the subject. Regular expressions are also described in the Perl documentation and in a number of other books and online resources, some of which have copious examples. There are many web sites that serve as online repository of useful regular expressions. The description here is intended as introductory documentation only.
The most trivial example is to use plain text keywords as matching pattern. Pages that contain those words will be used as a successful match.
For example: using "Johnson" as a matching pattern will result in extracting all pages that contain this text (assuming that output option is a set of all matching pages). Although this simple query is useful, we might want to define more complex patterns. The power of regular expressions comes from the ability to include alternatives and repetitions in the pattern. These are encoded in the pattern by the use of meta-characters, which do not stand for themselves but instead are interpreted in some special way. There are 11 special meta-characters:

Character	Description
\	general escape character with several uses
$	assert end of string (or line, in multi-line mode)
.	match any character
[	start character class definition
|	start of alternative branch
(	start sub-pattern
)	end sub-pattern
?	extends the meaning of ( also 0 or 1 quantifier also quantifier minimizer
*	0 or more quantifier
+	1 or more quantifier also "possessive quantifier"
{	start min/max quantifier
!	negate the result of regular expression

It's impossible to cover all details of regular expression syntax in this brief introduction. See www.regular-expressions.info for detailed information.
Here are few useful examples that will help you utilize some powerful features of regular expressions:

Matching alternatives: Vertical bar characters are used to separate alternative patterns. For example, the pattern Johnson|Peterson matches either "Johnson" or "Peterson". Any number of alternatives may appear, and an empty alternative is permitted (matching the empty string). The matching process tries each alternative in turn, from left to right, and the first one that succeeds is used.

Sub-Patterns: Sub-patterns are delimited by parentheses (round brackets), which can be nested. For example, the pattern ((red|white) (BMW|Volvo)) matches all combinations of "red" and "white" with words "BMW" and "Volvo" (i.e. "red BMW" or "white Volvo"). Another example: (sens|respons)e and \1ibility matches "sense and sensibility" and "response and responsibility", but not "sense and responsibility". If instead the pattern (sens|respons)e and (?1)ibility is used, it does match "sense and responsibility" as well as the other two strings. The meta-character \1 here serves as a back reference to the first matching sub-pattern. Such references must, however, follow the sub-pattern to which they refer.

Matching two patterns simultaneously: Sometimes it's necessary to match two or more patterns simultaneously (logical AND). Regular expressions do not provide AND operation directly. However, it's possible to write a regular expression to produce desired behavior. For example, the pattern (John Smith).*(Expense Report) matches all pages that contain "John Smith" and "Expense Report" strings together. This expression consists of 3 parts:
    1. (John Smith) - matches "John Smith" string
    2. .* - matches 0 or more occurrences of any character.
    3. (Expense Report) - matches "Expense Report" string.

Matching whole words: Simple text patterns such as Alert are also going to match words "Alerts", "Alerted" and etc. If you want your pattern to match only whole words, surround it with \b meta-characters. For example, use \bAlert\b to match only word Alert and exclude all other words that might contain it as a sub-string.

Matching sub-string: If text that you want to match should appear only inside bigger word, use \B meta-character. For example, the pattern \Bword\B will match word "swordfish", but will ignore words "word", "words" and "password".

Repetitions: The general repetition quantifier specifies a minimum and maximum number of permitted matches, by giving the two numbers in curly brackets (braces), separated by a comma. The numbers must be less than 65536, and the first must be less than or equal to the second. For example: z{ 2,4} matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special character. If the second number is omitted, but the comma is present, there is no upper limit; if the second number and the comma are both omitted, the quantifier specifies an exact number of required matches.

Negating the result: Sometimes it's necessary to match text that does contain certain words or patterns. This can be done by adding ! as a first character of the regular expression. For example, !(Approved) matches any string that does not contain word "Approved" in it.

Character types: backslash can be used to specify generic character types:

\d any decimal digit
\D any character that is not a decimal digit
\s any whitespace character
\S any character that is not a whitespace character
\w any "word" character (A "word" character is any letter or digit or the underscore character)
\W any "non-word" character

For example: \d{8} matches exactly 8 digits.

3. 7. Batch Processing (available in AutoSplit Pro and AutoSplit eCTD)

            Acrobat software provides a batch processing facility that allows you to create batch sequences and apply them to multiple documents at once. AutoSplit plug-in installs "Split Document" and "Merge Documents" commands that can be accessed and executed via "Batch Sequences" dialog. These commands may be used alone or inside another batch sequence allowing you to incorporate document splitting procedure into your existing workflow. You need Acrobat Professional in order to have batch processing available on your system. The section below outlines the procedure to use when creating a batch sequence for splitting documents. You can use the same procedure to create and configure batch sequences that use "Merge Documents" command. However there is one fundamental difference in the way these two commands handle input document. "Split Document" command take input document and splits it into multiple. "Merge Documents" command uses its own list of input folders and documents and essentially ignores input document that is passed to it by Acrobat batch processing framework.
           
3.7.1 Creating a document splitting batch procedure

1. Select "Advanced / Batch Processing…" from Acrobat's application menu. "Batch sequence" dialog will pop up on the screen.
2. Click "New Sequence…" button and type in a name for the new sequence. For example, type "SplitByBookmarks" and click "OK" button.
3. Click "Select Commands…" button in "Batch Edit Sequence" dialog.
4. Select "Document / Split Document" from the list of available commands in "Edit Sequence" dialog and click "Add>>" button.
5. Now you should see a new "Split Document" entry in the sequence list on the right side of the dialog.
6. Double click on the "Split Document" entry (on the right side of the dialog).
7. "Split Document Settings" dialog pops up on the screen. Select desired splitting method and processing options. These settings will be saved as part of your new batch processing sequence. Click "OK" button to save settings and continue.
8. Click "OK" button in "Edit Sequence" dialog.
9. Set "Select output location" option to "Don't save changes". Click "OK" button in "Batch Edit Sequence" dialog.
10. Now you have created a new batch processing sequence that can be used on single or multiple documents. This new command will be always available as custom processing sequence in future sessions.

            3.7.2 Running a document splitting sequence

1. Open "Batch Sequences" dialog by selecting "Advanced / Batch Processing" from Acrobat's main menu.
2. Select desired sequence from the list and click "Run Sequence" button.
3. Click "OK" in confirmation dialog and Acrobat will prompt you to select input documents. Make sure that documents you want to process are not currently open in Acrobat viewer.
4. Select one or more input documents and click "OK" button to start processing.

            3.7.3 Starting a document splitting sequence from a command line prompt

            AutoSplit plug-in can be launched from operating system command line prompt or from a batch file. Use any text editor (for example, Notepad.exe) to create a batch file that will be executed from the command line. The following is a sample batch file assuming Acrobat 7.0 is located in default installation folder:

SET AUTOSPLIT=C:\Documents and Settings\YourLogonName\Application Data\Adobe\Acrobat\8.0\Sequences\SplitSingle.sequ
"C:\program files\Adobe Acrobat 8.0\Acrobat\Acrobat.EXE"

Note that this batch file contains two lines of text, not one. Make sure you specify correct location and name of the batch sequence file you want to execute. Replace YourLogonName in the path with your real login name. It's generally a good idea to verify if a sequence file you specify actually exists. If you are not using Adobe Acrobat 8.0 than you have to make necessary changes to the Acrobat.exe and batch sequences folder paths. Save this batch file to a disk and make sure it has BAT extension. For example, save it as "Autosplit.bat".

            If you need a better solution for creating and executing Acrobat batch sequences then take a look at AutoBatch plug-in that is specifically designed for this task.

Executing batch file from command line:

• Make sure Adobe Acrobat is not running on your system.
• Open a folder where your command line batch file is located.
• Double click on the batch file. Adobe Acrobat should launch and immediately start executing a batch sequence.
• Acrobat will automatically exit once processing is completed.       

3.8  Executing

Click "OK" button on the "Split Document Settings" dialog to execute document splitting operation. If "OK" button is disable, it means that selected splitting method is either not-applicable to input document or requires selecting of additional parameters.

4. 1. Merging Multiple Documents

Document merging dialog can be started from Adobe Acrobat menu, by selecting "Plug-ins / Merge Documents...".  "Merge Document Settings" dialog will pop-up on the screen. Select desired document merging operation and input documents and click "OK" button to execute operation. New document will be created by combining input documents together according to selected settings and opened in the viewer. This document will be temporary named "MergeResults" and will need to be saved to a permanent file by a user unless "Save document as" option is selected and output filename is specified.
Check "Pad input document with a blank page..." option to automatically add blank page to the end of each input document that has odd number of pages. This option helps to ensure that first page of each input document will start on the odd page (front side of the page in the double-sided printouts) in the output document.

4. 2. Merging Documents by Appending Pages

- Select input documents that need to be merged by clicking on "Add Document..." or "Add Folder.." button. File selection dialog should appear on screen. Select desired documents and click "OK" button. Selected documents will be added to the list of input documents. The order of the files in the list determines their processing order.
- Double-click on the file in the list or select a file and click "Set Page Range..." button to optionally specify range of pages to use.
- Select processing mode by picking "Append Pages" from "Merge Operation" menu.
- Click "Save..." button to optionally save processing settings (including selected input files) to a settings file. This file can later loaded by clicking on the "Load..." button.
- Click "OK" button to start merging documents.

Pages from multiple input documents are sequentially copied (appended) to a new output document. User can optionally specify a range of pages to use from each input document. Software proceeds as follows: first selected pages from first document are copied to the output, then pages from the second document are transferred and so on. The resulting PDF document is opened in Adobe Acrobat as "MergeResults" document that needs to be saved to a file by a user.

4. 3. Merging Documents by Interleaving Pages

- Select input documents that need to be merged by clicking on "Add Document..." or "Add Folder.." button. File selection dialog should appear on screen. Select desired documents and click "OK" button. Select documents will be added to the list of inputs. The order of the files in the list determines their processing order.
- Double-click on the file in the list or select a file and click "Set Page Range..." button to optionally specify range of pages to use.
- Select processing mode by picking "Interleave Pages" from "Merge Operation" menu.
- Specify number of pages from each document to interleave in "Number of pages to interleave" entry box. This number should be always greater than zero.
- Click "Save..." button to optionally save processing settings (including selected input files) to a settings file. This file can later loaded by clicking on the "Load..." button.
- Click "OK" button to start merging documents.

Pages from multiple input documents are sequentially interleaved and copied to a new output document. User can optionally specify a range of pages to use from each input document. Software proceeds as follows: first N pages from first document are copied to the output, and then N pages from the second document are copied and so on. This process is repeated until there are enough pages in each document to proceed. If there is not enough pages in one document, the plug-in will start looping pages from the beginning. For example, if you have document A (200 pages long) and want to insert document B (2 pages long) after every 2 pages of document A, then software will repeat pages from document B as many times as necessary to complete this task.
You need to specify a correct number of pages to use from each input document to achieve correct results. For example, if you selected two files A and B as input documents and specified "1" as number of pages to interleave, then output document will look as follows: page 1 from A, page 1 from B, page 2 from A, page 2 from B, page 3 from A, page 3 from B and so on. The resulting PDF document is opened in Adobe Acrobat as "MergeResults" document that needs to be saved to a file by a user. 

4. 4. Merging Content of the Folder

All PDF documents in the folder can be merged by adding a folder to the list of input document. The software will automatically determine the list of PDF documents in the folder at the run-time. Click "Add Folder..." button to select a folder. You will be prompted to specify folder processing options:
- Check "Include documents from all subfolders" option to add PDF documents from subfolders to the list of input documents.
- Check "Sort documents alphabetically before merging" option to sort documents before merging using their full paths. This option will affect the order of the pages in the output document. There are two possible sorting orders: "Ascending" and "Descending". Subfolder names are also used when determining sort order of the input document. For example, you have 3 documents in the input folder: C.pdf, A.pdf, and B.pdf. If "Ascending" sort order is specified then documents will be merged in the following order: A.pdf, B.pdf, and C.pdf. If "Descending" sort order is selected then files will be merged in the different order: C.pdf, B.pdf, A.pdf.
You can always modify folder processing settings by double-clicking on the folder entry in the "Documents To Merge" list.

4. 5. Batch Processing (available in AutoSplit Pro and AutoSplit eCTD)

            Acrobat software provides a batch processing facility that allows you to create batch sequences and apply them to multiple documents at once. AutoSplit plug-in installs "Split Document" and "Merge Documents" commands that can be accessed and executed via "Batch Sequences" dialog. These commands may be used alone or inside another batch sequence allowing you to incorporate document splitting procedure into your existing workflow. You need Acrobat Professional in order to have batch processing available on your system. The section below outlines the procedure to use when creating a batch sequence for merging documents. "Merge Documents" command uses its own list of input folders and documents and essentially ignores input document that is passed to it by Acrobat batch processing framework.

4.5.1 Creating a document merging batch procedure

1. Create a new batch sequence (for example "Merge") using "Advanced / Document Processing / Batch Processing" menu.
2. Set “Run commands on” to “Existing file” option.
3. Specify any bogus existing input file for this sequence. This file will be actually ignored during processing. Acrobat batch processing is designed for a pipeline-style processing of a single document. It does not fit well for complex multi-file operation as file merging.
4. Select "Don't save changes" for "Select Output location" option. Input/Output files are selected inside a "Merge Documents" command.
5. Click "Select Commands" button.
6. Add "Document > Merge Documents" command to the sequence.
7. Click "Edit..." button or double-click on just added command.
8. This will open "Merge Documents Settings" dialog.
9. Specify all necessary input files and folders.
10. Specify "Output Document" for merging results.
11. Click "OK" to save this changes to a command.
12. Close all batch sequence dialogs by clicking on "OK" buttons.

            4.5.2 Running a document merging sequence

1. Open "Batch Sequences" dialog by selecting "Advanced / Batch Processing" from Acrobat's main menu.
2. Select desired sequence from the list and click "Run Sequence" button.
3. Click "OK" in confirmation dialog to start processing.

5. 1. Why plug-in might not load?

If you have successfully downloaded and installed a plug-in but can't find it in the "Plug-ins" menu, then make sure that "Use only certified plug-ins" option in Acrobat application preferences is not set:

1. Start Adobe Acrobat and select "Edit > Preferences..." from the main application menu.
2. Select "General" group of settings (Acrobat version 8) or a "Startup" (Acrobat versions 6 and 7).
3. Make sure that "Use only certified plug-ins" option is OFF.
4. Save settings and restart Adobe Acrobat.

Sometimes (if Adobe Acrobat is running silently by a web browser), it might be necessary to restart your computer in order to let Acrobat to recognize a newly installed plug-in.

One of the other possible reasons (but extremely rare) is that there are too many plug-ins already loaded by Adobe Acrobat viewer. There is a limit to the number of plug-ins that can be loaded by the viewer at any one time. The number is variable and dependent on the code generation settings of all loaded plug-ins. Solution: Remove some of the Adobe Acrobat plug-ins to reduce number of plug-ins simultaneously used.
