How to hide files and folders on your Java phones

In life we all have Documents we don't want our family and friends to see...really And we all wish we could hide them,our wish has finally come to pass then.
Steps
1.Go to the area where u want to hide files (gallery/ applications)
Create a folder-
FolderName.jad
2.Add the files needed to be hidded to this folder
.
3.Create an another folder, where the FolderName.jad is located. Name it as-
FolderName.jar
4.Now the 1st folder will not be visible.. But after renaming FolderName.jar to
some other like-
FolderName.jara
the 1st folder will be visible and u may access it..
U may name the both folders as u like.. For eg: 'a.jar' and 'a.jad'
