Thanks to XDA developer ppero196, there is a quick and simple little tool to help clear out the extra garbage. Doesn’t get much easier than installing the app, opening it and hitting a button does it? That’s it. That is all it does. Finished. So if you have never ever cleared out those thumbnails ever in your life, you might want to give it a whirl. You can head over to ppero196′s XDA thread for the link. Oh ya, you can also set it to remind you every month to clean out the trash.
Update: The developer of this great app has just put out another new update. The app can now delete from internal and external sources. Also there is a new widget to add to your homescreen, but it looks like the button isn’t working yet. I am sure that will be fixed soon.
App now shows free space before deletion, and after clicking delete button, after deletion
Updated landscape layout for new changes
