How do I free disk space?

Click the Cool Menu icon on the menubar. Go to "Free Disk Space". Here, you will see one entry that says "Delete All" followed by multiple other menu items. Clicking on "Delete All" will delete unneeded data from all locations pointed to by all the other menu items. Clicking on an individual menu item will delete unneeded data from only that location pointed to by the particular menu item. In either case, the first time you click any menu item, the app may seek your permission for your home folder by displaying an Open panel (which is required as per Sandbox regulations). Since the home folder will be selected by default, all you have to do is click the Open button on the dialog box. Thats it. Wait for the app to complete the cleanup process. A final confirmation message will be displayed to you that says how much disk space was recovered.
