Clean Out the Application Support Folder(s)
Most applications contain their major resources inside the application file. However, some place a large amount of data in their application support folders. There are general and user-specific application support folders (inside the Library folders in both user home folders and at the root level of the hard drive). If you delete an application, be sure to delete the associated support folder. Also, for some applications, there might be resources stored in those folders that you don’t want (some of the themes for iDVD or loops for GarageBand, for example). Selectively cleaning out these folders can help recover disk space, although caution (and a backup) is advisable if you plan to keep using the application.
