I downloaded Google Desktop a while ago, and was a little disappointed that you couldn't specify which file types to index. Specifically, wouldn't it be nice to index your source code? Then, when you have a problem, and you know you've done something like that before, you can search your local drive for it. To me, that would make it much more useful.

So that's why I was happy to see this site. With this, now you can specify which file types to search, and Google Desktop will index them.

One word of caution. It involves installing hacked versions of the desktop executables and registry editing. So if that bothers you, go ahead and skip this one.
