File comparison tool

[Bob Flynn]

Beyond Compare is what I use at work. Kdiff is another favorite of some at my work.

I like the merge tool that comes with Perfoce. Work uses subversion for source control but I still use the merge tool out of perforce with it (which is free).

Subversion and Tortoise SVN usually because it's a file I'm working on in a project.

Ditto Beyond Compare

I second the "Beyond Compare" because it is integrating in the Windows Explorer and can compare binary files.

Araxis Merge is excellent: http://www.araxis.com/merge/[^] Does 2 and 3-way merging. Not free.

Best wishes, Hans

Beyond Compare[^] has may nice features: - compare/sync folders - sync from/to zip files (quick way to edit a file within a zip file) - compare sync text files per selection/line - inline text editing, while comparing files - option to ignore unimportant changes, like source code comments - compare images - save/load sessions ... and much more :)

second WinMerge and Beyond Compare. Use both regularly

Yusuf Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

My vote too, best 3 way merge I've ever used. Don't know how anyone can live with only 2 way merge :-)

[Phil Martin]

It's the second best three-way merge I've used. For complicated diffs I reckon KDiff3[^] has it beat hands down. Things that Araxis had much trouble deciphering KDiff handled fine, and did an automated merge for me, even across directories. It's saved my bacon a number of times.

I use Meld [http://meld.sourceforge.net/index.html\]
