When a file and path name exceeds about 255 characters, which we have recently breached with backup systems, our archive PDFs do not open in Adobe. However, if we open them in other programs, they will open fine, but we need to be able to edit them, which leaves us having to copy the files out of their long path into a shorter path, make the changes, and copy the file back. If other programs have the ability to open long file paths, then it should be able to do so in a 64 bit digital age.
