How to reset IntelliJ idea settings in Mac

Recently I had difficulty working with Intellij Idea on MAC (MAC OS X verson 10.6.7) and I wanted to reset the complete setting of Idea and start from the beginning but without reinstalling Intellij Idea. It was very easy ..

Delete following directories and start Intellij Idea again and you will be asked to give the license key again and my issues got fixed when I reset the settings.

1. ~/Library/Caches/IntelliJIdea10

2. ~/Library/Preferences/IntelliJIdea10

I wanted to blog quickly before I forget.. Hope this helped !
