KDiff3 plugin

Among the programs used to compare files and show the differences (Diff programs), one stands out: Open-Source freeware KDiff3 can compare or merge up to three files. Reason enough for blechtrottel.net to develop a plugin for phase 5.

KDiff3 plugin by blechtrottel.net

version history


  1. Download and install KDiff3.
  2. From kdiff3.zip copy the files KDiff3.exe, %1-Zwischenablage.exe and kdiff3.ini in the plugins folder of phase 5.
  3. In kdiff3.ini, change the path to kdiff3.exe in the program. Done!

If necessary, change the order and selection of the files and select the mode (Diff or Merge): The files are opened in KDiff3.
