Is there any way to use the "compare documents" feature without violating security restrictions on a document? My firm has to regularly compare old and new versions of PDFs received from a vendor who does not provide us with the document password. It would be hugely beneficial to be able to use the "compare documents" feature for this but I am currently unable to. If we can figure this out it would give us a strong incentive for the rest of us to upgrade to pro.
BY security restrictions you mean encrypted, right? If a PDF is encrypted how can comparison work? The order of PDF objects in two PDF files may be different but the content is the same. Without ability to decrypt PDFs being compared it is impossible to compare their content. I am just curious: what do you do with PDFs that you cannot open and see what's in them? If you cannot see then and the comparison somehow magically works then you'll at least see the differences and that is what encryption is designed to prevent.
I have a similar question - but not involving encryption. Is it possible to set up a file so that it is:
can be compared with other files with similar or lesser protection
is write protected
ideally - but not essential - it is also copy protected?
This should preferably be by password protection.
And if so - how?
