That's what I've done and at the risk of repeating things which have already been said in other ways, here is the simple advice I give my coworkers. Maybe it helps someone who stumbles onto this thread. How to set up Beyond Compare as your external merge tool in Bazaar Explorer 1. Install bzr-extmerge 2. Launch bzr-explorer; navigate to Settings > Configuration > User Configuration 3. Activate the Merge tab. 4. Add entry: c:\Program Files\Beyond Compare3\Bcomp.exe /ro %b %o %t %r Note: the second and third file macros are mapped to the right and middle Beyond Compare panes, respectively! 5. NEVER click on the Resolve Conflicts icon in the bzr-explorer "What's next?" pane. 6. ALWAYS right-click on the conflicted file in the Working Tree and use "Merge conflict" and "Mark conflict resolved" This seems to work pretty well for us, except when someone thinks he's too smart to follow instructions. :) Note: It would be nice if extmerge simply did argument substitution, but it seems to reject tool-specific options which run into the file placeholders. For example, BC3 understands thin /vcsleft=<file> but ext-merge rejects /vcsleft=%b. Not a big deal but potentially aggravating for someone trying to use the command-line recommended by their merge tool.
