How to add multiple file extensions to the search inside feature in WIndows 7?

Question

I know how to add a single file extension to be searched inside, but I'd like to add a bunch of different extensions and avoid the tedious job of adding every single one.

Is there a command line tool or registry key I can use to accomplish this?

Answer 1

You can search multiple file extensions in Windows Search with filters like this:

ext:.txt OR ext:.doc OR ext:.rtf
