Lock Folder in XP using DOS

Lock Folder in XP using DOS
the best way to hide a folder is using the commands(locking)
it is very simple
suppose if the folder games in d: drive
once it is done open run->cmd

for locking the folder
d:\(name of the folder in drive d) /d everyone

for unlocking type
d:\(name of the folder in drive d) /g everyone:f

once u hav locked a folder and if anyone tries opening it a message access is denied will be displayed. u dont hav to hide a folder after doing this.
