WinMerge

This is an old version of WinMerge, for the latest version go to the main site.

Known Limitations

• Sometimes you cannot merge two files because the program says they are binary, even if they are mostly text files.

  Workaround: Use the new EditBinaryFiles.dll plugin.

• There is no way to specify the codepage for a particular file.

  Workaround: Specify the default codepages for all files in Edit->Options->Codepage->Custom codepage.

• There is no 3-way merge.

• $ does not match end of line in linefilter regular expressions

  Workaround: Construct your regular expression so that you don't need to use $.

• Filters only applied when using full compare

  Line filtering is only applied in folder compare when using Full Contents-compare method.

  If you are using any other compare method, line filters are not applied. Files marked different in folder compare can get status changed to identical when opening them to file compare.

• Some plugins shipped with WinMerge require Visual Basic runtime library to work

  Workaround: You can download the required file msvbvm60.dll or use the Run-Time Redistribution Pack from Microsoft.

  Workaround 2: If you don't need the plugin, you can safely remove it.

• VSS integration cannot add new files to VSS

  If you need to add a new file, you must add it via VSS client program.

• Unset WinMerge integration from ClearCase

  To remove WinMerge integration, you'll need to edit one file by hand:

  1. Find ClearCase installation folder
     Usually it is something like C:\Program Files\Rational\ClearCase
  2. Go to subfolder lib\mgrs\
  3. Open file map in there to editor program
  4. Comment-out the line starting with "text_file_delta xcompare", containing "WinMergeU.exe"
  5. Uncomment the line starting with "text_file_delta xcompare", containing "cleardiffmrg.exe"
