Need code to merge PDF files in a folder using adobe acrobat X

[yuechu]

Thanks ZVI. I see that the file does have password protection in it even though it does not ask for any when I open it. I tried it with some PDFs I created and the macro worked perfectly.

My next steps will be to only merge similar PDF files (files beginning with same filenames) out of the bunch of PDF file in the folder and then renaming the merged file to a corresponding name on a list. Any tips of the best way to do that?

Hi and welcome to VBAX!

You can't insert new page after the PDF document with password protection has been inserted.
Have a look on protection property of the last document inserted into the resulting file MergedFile.pdf
