Hide ur folders without the usage of folder lock

suppose u want to hide a folder named abc which is in D: of ur computer

go to command prompt
start--->run--->cmd-->d:


after changing it from C: to D:

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

to show the folder

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