Hide your data in a mobile.

1. Select a folder that you want to hide or create a new folder and place all those files in it that you want to hide.
2. Give that folder any name but with extension of .jad ( for ex. ABC.jad)
3. Now, you have to create new folder with same name but this time the extension should be .jar ( for ex. ABC.jar)
4. Your folder will become invisible. In case you want to unhide that folder, you have to just delete the .jar extension from the visible folder.
