Please take a look on WWW and you will find that:
1. TC is not required,
2. simple "step by step how to" if written down there (even with movie).
I agree that mention should be made in the first post that TC isn't required. I had to dig deep to find out if this works without TC. I think you'd have more users.
Isn't it possible to create a registry key to use Comparer via the context menu? Something like
""drive:\path\Comparer.exe" %1 %2"
I'm not familiar with the formatting and you can't google search "%1".
If this was directly accessible from Explorer it would always be one of the first things I installed. It should be built-in as default. Thanks for sharing.
