This is just a donation for Shortcut for Storage Settings application.
By installing this application is a way to show some appreciation for my work.
The application Shortcut for Storage Settings should be installed first: http://goo.gl/EShJzJ

Donation version is not actually an application is more like a key used by the Shortcut for Storage Settings application to check the donation made.
By donating, the main application functionalities are not changed.

Thank you very much for your appreciation!
