Windows Explorer - Diff two files from the context menu?

Question

Is there any way to diff two selected files from the context menu in Windows Explorer?

Answer 1

Sounds like you need diff-ext!

This shell extension (diff-ext) makes it possible to launch file comparison tool for 2 or 3 files (depending on the tool) in the same directory or "save" a file(s) for later comparison. It acts as external most recent used (MRU) file list for the comparison tool.

I'm using it with KDiff3, but there are a number of other diff tools on the page it can be used with.

Answer 2

Beyond Compare and WinMerge can also do this if you enable Shell Integration during the installation.
