How do you password protect multiple PDF files at once?

I have tried compressing the files into a zip folder and adding a password (with the compression tool built into XP), but after 4 days it was only about 30% finished and it came up with an error "Cannot create output folder" (the disk wasn't full).

I have Acrobat 9, which I can password protect one document at a time, but this would take days to complete.

Are there other ways to password protect large numbers of documents at once?  (approximately 30,000 files)

Can you not password-protect a folder which has all 30,000 of them in it and limit access that way?

They wanted the individual documents themselves protected also.

I figured out that WINRAR will protect the entire compressed file, while the XP compression tool will password protect them individually (which keeps failing at different places).

I don't have a problem password protecting the entire directory which is already done, but the individual documents inside will be sent to different people without sending them the whole directory.

If you have Acrobat Pro you can set security options via Batch Processing. I am traveling at the month so don,t have this in front of me but I believe you find this under Advanced.

Select and set up a new sequence then specify security options from the list. Set your desired options and click through OK. Select run options and output folder.

This should do it.
