This is just a donation for DSC Auto Rename application.
By installing this application is a way to show some appreciation for my work.
Android 11: This application DOESN'T work on Android 11!
The application DSC Auto Rename should be installed first: http://goo.gl/ZyYjnx

Donation version is not actually an application is more like a key used by the DSC Auto Rename application to check the donation made.
By donating, the main application functionalities are not changed.

Thank you very much for your appreciation!
