MergeFiles

Document manipulation

Description

Merges two files on disk and saves the merged document to a new file. The files are accessed directly on disk, the entire file does not have to be loaded into memory so this function can be used with huge documents. The files must not be encrypted. Monitor the size of the output file while this function runs to work out the progress.

Outlines (bookmarks), form fields and annotations from the both documents will be present in the merged document.
