Hello, I have a large data set of PDFs that need to be indexed and keyword searched. My indexing software has reported that around 1,500 of these are password protected.

When I started to review these they open fine without any password request. I believe that the software is identifying that the files have an ownership password, this is a not a problem as we can index these fine. However, is there a way to identify password protected files which doesn't allow you to read without going through them on at a time?

Thanks

Mark

What software are you using to index? Some software doesn't allow ANY security on the PDFs in order to index, while others will work for all but open passwords.

However, to answer your question, there are a variety of ways in which you could determine which files are encyrpted and which are not.

I have produced a lot of technical manuals as pdf files. To avoid the users (customers) to make changes in the files, I have protected them with a password. Only printing in hi res is allowed. Now some of the customers want to index the manuals. How can I allow indexing in password protected pdf documents?

Nothing is so complicated that it cannot be explained in images and symbols.

I am a truly a neophyte so forgive me ....

In Acrobat 8 Pro, I am attempting to insert Bates numbers using Advanced > Document Processing > Bates Numbering > Add.The message returned on all my files is that this function cannot be performed on this file because it is "protected".

I have attempted to remove whatever protection may exist on the files.
The files were never password protected.
I ran a batch sequence and removed all security and tried the Bates feature again, but no success, same message, i.e., can't bates number because 'protected'.

I am not even clear on what 'protected' means (because I removed all security on the files and never took steps to affirmatively protect documents) and have less of a clue at this point as to how to remove the mysterious 'protection'.

Any help is greatly appreciated.
