Can I replace internal diff in Total Commander with a custom tool?

Solution 1:

There are many ways to do this (here I'm using BeyondCompare as an example, it's the best I've found in this category, but the solution also works well with WinMerge):

A) Edit wincmd.ini under %USERPROFILE%\AppData\Roaming\GHISLER\ by default, and add something like this:

[Configuration]
CompareTool=C:\Program Files\Shareware\FileCmp\BeyondCmp\BCompare.exe

Now all comparisons are made using this app instead of the internal tool.

B) Using TotalCmd's StartMenu (command "Change start menu..."), add these commands:

Title:

BC (Compare left-vs-right directories)

Command: %YourPath%\BeyondCmp\BCompare.exe

Parameters: %X%p %X%t

Title:

BC (Compare current file under cursor vs same file in the other panel)

Command: %YourPath%\BeyondCmp\BCompare.exe

Parameters: "%X%p%x%n" "%X%t%x%n"

Title:

BC (Compare current file in left vs current file in right)

Command: %YourPath%\BeyondCmp\BCompare.exe

Parameters: "%X%p%n" "%X%t%m"

Solution 2:

I came accross this question because I wanted to use Visual Studio Code as external diff tool.

Since VS Code isn't primarly a diff tool one can't just invoke the exe-file with two filenames as parameters. Instead the option --diff or just -d has to be specified.

This is important when editing the WINCMD.INI. The line Comparetool has to take the path to code.exe and the diff-option:

[Configuration]
Comparetool="C:\Program Files\Microsoft VS Code\Code.exe" --diff
