THIS IS REALLY WONDERFUL TRICK ..................)
hide your folders without the usage of folder lock :

suppose you want to hide a folder named abc which is in D: of your computer

1. Go to command prompt
Start--->Run--->type cmd-->type d:

after changing it from C: to D:

type D:/>attrib +h +s abc
the above command is to hide the folder

type D:/>attrib -h -s abc
to show the folder

n this type of hiding the folder cannot be viewed even if we make advance search or even changing the folders menu to (show all hidden files)

(YA FRIENDS ITS REALLY COOL U CAN EASILY HIDE UR FOLDERS)
