xdocdiff WinMerge Plugin

Japanese page

What's this?

This is a plugin for WinMerge (an Open Source diff tool).
This plugin is tested with WinMerge 2.8.6, the latest version on release date.
May not work well with other versions of WinMerge.
With this plugin, you can compare these files.

Word and Excel diff plugins are bundled with WinMerge.
But those plugins require Word or Excel to compare files.
xdocdiff Plugin does not require Word or Excel, and it's faster to show differences.

If you are using TortoiseSVN, please try xdocdiff, too.
