I miss the TreeComp tool from Windows on Linux. Does anybody know about a similar tool for Linux?

I've tried Unison & Unison-gtk (slow and cumbersome), diff (various), meld, mc, rsync (immensely configurable, my actual solution for backing up things, but not interactive), etc.

Regarding Unison: It can be slow if you are using it on a network filesystem directly, due to the consistency checks Unison makes. However, it becomes really fast if used over SSH. – grawity Dec 26 '11 at 12:31
As I read in the TreeComp description, it is just a GUI for the windiff program, and the source for that program is available ( So you could take that as an example (you can't port that to UNIX) and make a neat X11, Qt or Gnome version of it. – ott-- Dec 26 '11 at 12:40
I did not read the docs but I used the program for many years... The strong feature of TreeComp is the ability to sync entire branches just by rightclicking on the top node of the branch :) – atrent Dec 26 '11 at 16:45

Take a look at FreeFileSync.

very close, thank you the only negative remark about FreeFileSync is that it shows the differences using a "spreadsheet" GUI component instead of a collapsible tree – atrent Dec 26 '11 at 16:37
@atrent That's no longer the case, at least in the Mac version of the app. – Matt Passell Jul 14 '14 at 20:01
