I'm using Acrobat Pro, ver 8.1.2 on Win XP Pro and attempting to reclaim space on my hard drive. Search found 450 *.txt files (nearly 10Mb) in various C:\Program Files\Adobe\Acrobat 8.0 sub-directories (e.g., Acrobat, Designer 8.0, Resource, Setup Files) as well as in C:\Program Files\Common Files\Adobe\TypeSpt\Unicode\Mappings\ (e.g., Adobe, Mac, win). Can anyone please advise if any or all of these files are required for operation of the program or whether they can be deleted? It would seem obvious the "Mac" files could disappear for me since my machine is Win, but I don't know about the others. Many thanks. ~Allan
