Created attachment 175479 [details] Screenshot showing error message I have successfully used KDiff3 with TortoiseGit on Windows for years. Unfortunately, Kdiff3 1.11.* breaks the integration. When requesting a diff of most files, an error dialog appears that says "Opening of Files Failed". See attached screenshot. By most files, it happens to about of 80% of files - ever so often one works. I have not discerned a reason as to why. Reverting to KDiff3 1.10.7 resolves the issue. STEPS TO REPRODUCE 1. Install TortoiseGit on Windows 11 (I'm using 2024H2) 2. Checkout a Git repo 3. Modify a file 4. Right click the file, select TortoiseGit | Diff. 5. See error message I have setup KDiff3 following the TortoiseGit instructions here: https://tortoisegit.org/docs/tortoisegit/tgit-dug-settings.html Meaning, the command line used to run KDiff3 is: C:\Path-To\kdiff3.exe %base %mine --L1 %bname --L2 %yname
