Have a look at FreeVCS - it has a good diff-style utility. http://www.freevcs,org

But you could get the source code for their utility from there I think.

what kind of comparing are you needing? I do not know the  'diff'  program.  You could just run through both files and see if any bytes are not the same, however if you want to compare the (I guess text) file data to find chunks that  may have been removed, it can get kind of complicated

You will find a free TDiff component and utility (Delphi) at Angus Johnson's web site http://www.users.on.net/johnson/delphi/
