Looking at my Applications folder, I have no duplicate applications, yet when I right click files the Open With dialog often has a massive list of applications full of duplicates.

Why is this?

(OS X 10.8.2)

A cache file has been corrupted. You can reset the cache file with a simple /Applications/Utilities/Terminal.app and at the first Terminal prompt put in the Terminal code (after you quit all Applications):

Code:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

After you let the Terminal program run and know it reset the cache you will know it is finished when you get another Terminal prompt. Then you can close Terminal and the right click for applications will work correctly again. Good Luck.

Thanks! This works fine.

Interestingly enough, while the cache file can be reset successfully, it becomes corrupt again after days or weeks of usage. Even more strange, it only becomes corrupt again on a 13" MBP running 10.8.2 but not on a 24" iMac running the same software.

The Terminal fix worked for me on a 27" 2011 iMac. It's worth noting that even the Finder must be relaunched for the change to take full effect - you really DO have to quit everything.
