UPDATE NOVEMBER 2017: This action no longer works and the links to it have been removed.

There is a newer version of Compare Folders.

The new version adds the following features and bug fixes:

* Log generation option, which creates a text file in Text Edit of your comparison results.

* Now checks to ensure that the items you’ve selected are folders. If you hand it something other than a folder, it exits gracefully.

You can download the new version here.

Thanks for checking.
