How to hide Folder in java mobile

1.First you create any folder For example game2. Now give game  folder any name but with the extension of .jad for example if you want to hide game folder then I will give name as game.jad

3. Now you have to create a new folder in the same directory and with the same name but with the extension of .jar ie, game.jar

4. Here, I will create a new folder with the name game.jar

5. So Now You are done!! The original games folder has been hidden and now the folder visible is game.jar which is an empty folder. To view games folder that is to see our protected data,we need to remove the .jar extension from the games.jar and my original folder with my protected files and .jad extension will be visible.
