RCDefaultApp is a Mac OS X 10.2 or higher preference pane that allows a user to set the default application used for various URL schemes, file extensions, file types, MIME types, and Uniform Type Identifiers (or UTIs; MacOS 10.4 only). MacOS X uses the extension and file type settings to choose the application when opening a file in Finder, while Safari and other applications use the URL and MIME type settings at other times for content not related to a file (such as an unknown URL protocol, or a media stream).

got to figure out how to map nntp urls to google groups in default web browser

this has helped me solve so many file association issues on my mac, thus avoiding the dreaded refreshing/resetting of launch services (which is a huge pain). kudos to the folks at rubicode :]

I agree with kadis. Although not terribly useful on a day to day basis, I can't imagine using a Mac without it...

This is one of those apps that should be built into the system. It's that nice.

I use this to set my default browser, feedreader and email program (Gmail Browser). It's extremely useful.

Fire and forget. I honestly don't remember what I have this set up to do, but it must be doing it well because I don't have to fool with it. :)

The ability to list extensions by application in version 2.0 is very welcomed. This is a must-have preference pane for anyone even half-serious about configuring their computers the way they want.

For the longest time whenever I clicked on a someone's AIM/iChat status web badge it would launch Adium (which I no longer use) instead of iChat. I used this app to change the default app for "aim" links to iChat. It's only tool I know of that will do this for you.
