Some version control systems do not support visualization
of file version comparison. For example, you can not find
such tool in CVS. However, most of them enable us to use external
difference finders. AthlantDiff is a small, powerful
and freeware tool, which is included into Devrace
Athlant.
AthlantDiff is very simple. If you would like to compare two files you should run:
diff.exe file1.ext file2.ext
And that is all! If the files are identical AthlantDiff will display the message: Files are identical. Otherwise you will visually see the differences.
This expert looks very nice and integrates with VSS really well. I have not extensively tested it yet, but it did pass a quick "can I work with it" test. (I use it with Visual SourceSafe 6). And what's also important: when I did find a few problems Devrace was able to fix them nearly the same day. >>
