Hide data folder in mobile without any software

HIDE DATA FOLDER IN MOBILE WITHOUT ANY SOFTWARE

JUST FOLLOW SIMPLE STEPS

1. Create any new folder or you can use any existing folder that is to be hidden.

2. Rename the folder to any name but with the extension of .jad like if I want to hide my images folder then I will name it as IMG.jad


3. Now create a new folder with the same name in the same directory but with the extension of .jar So, I would create the folder with the name IMG.jar

4. And thats it!! My orignal images folder which has been renamed with .jad gets hidden and only folder with.jar extension is visible which is empty.So,my data is protected/hidden from unwanted eyes.

Note :This trick can be used for any JAVA phone from Nokia,Samsung,Motorola,LG or any other company.
To unhide the orignal folder you have to remove the .jar extension from the new folder and your orignal folder with all the files and with .jad will become visible....
