I would like to know if there is a way to automatically merge PDF documents so that a script (vbscript, not AutoIT) can be relied upon to merge documents.
Ideally, a command line approach or hot folder is what I am after.
You can with vbscript using IAC (InterApplication Communications) if you have Acrobat installed, and you're not using it on a server. More information is in the Acrobat SDK documentation. If you set it up to use a hot folder, only the licensee can be the one dumping the files into it.
