When using WinMerge in merge mode of Tortoise GIT you might be missing an information about the current file you working on. For this you can create a batch file and then start WinMerge with your informations.

The following batch file adds the name of the underlaying file for the merge in the header of the middle pane. The call for such batch file you have to place in the settings of Tortoise GIT for the Merge Tool as follows:

"<PathToYourBatchFile>\<YourBatchFileName>.bat" %theirs %base %mine %merged %tname %bname %yname

The content of your batch file can be like this:

@echo off

rem <summary>
rem Tortoise GIT enhancement batch (merge file name in middle tab)
rem <summary>
rem <revisionHistory>
rem   <revision version="2023.06.23" date="2023-06-23" author="Holger Boskugel, github.com/SphereSoftNET">Initial implementation</revision>
rem </revisionHistory>
