Hi friends this is cool trick to hide the folders in Nokia or any Java supported mobiles.  The special about this trick is that no softwares needed to hide the folder.
Hide the Folder:


!!! do this at your own risk !!!

Step 1:
Did you decide which folder you want to hide ? If you say yes,then rename that folder and add ".jad" extension to that folder.

For eg: if you want to hide the "Videos" folder.  then rename it as "Videos.jad".

Got it?
Step 2:
Now  create another folder with that folder name but with ".jar" extension.

For eg:
Videos.jar

That's all your Videos.jad folder is now hidden.  Only the Videos.jar folder is visible.

Unhide the Folder:
 To unhide the folder.jar  just delete or remove  the folder which ends with ".jar" extension.

For Eg:
I hide the Videos.jad foder.  Videos.jar folder is visible.  If i delete the videos.jar folder,then videos.jad folder will be visible.

!!! enjoy !!!
