Question: It has been discovered that several users have been uploading secured (password protected) .PDF into our document collaboration/review system. When a user is reviewing documents, and comes upon one of these, we get unexpected results (crashes, lockups, etc). I have been asked to determine where and how many secure PDF have been put into the file system (I don't even have a ballpark guess yet). Ideally, I'd generate a list of these offenders and we could remove them or save non-secure versions. The PDF are stored in a normal windows file system, with sub-folders for each individual upload session. Would there be any way to do this without opening hundreds of PDF? Some utility that could maybe "peek" for me? Any suggestions would be much appreciated on VeryPDF?
