CCleaner App Explained and Demonstrated
CCleaner is an app that will scan your device for unneeded files such as cache files, empty folders, installation files, and files left behind after you have uninstalled software. It will then give you the option to delete those files and free up needed space on your device.
CCleaner is currently available for all Android devices, Windows computers and Apple computers. It is not currently available for iPhone or iPad however, iCleaner should work the same way.
