Since I don't really like Total Commander's internal diff 'Compare Contents' used in Compare by content and Synchronize Dirs -> Compare left & right I want to use something else like Winmerge or KDiff3.
Is this possible to launch an external program with the paths to the marked files in the left & right pane? That would solve Compare by content. Any other way to solve it? Can I control Synchronize Dirs so it does the same when I compare file content there?
Any other suggestions to easily make diffs in Total Commander with external diff program?
