Hide your folders without using any software

Suppose u want to hide a folder named Coolitbox which is in E: of your
computer.
Go to command prompt
start--->run--->cmd-->E:
after changing it from C: to E:
type E:\>attrib +h +s coolitbox
the above command is to hide the folder
to show the folder
type E:\>attrib -h -s coolitbox
in 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)/activate show hidden files from folder options.
NOTE: here is "SPACE" between every character.
e.g. E:\>attrib(space)+h(space)+s(space)coolitbox
E:\>attrib(space)-h(space)-s(space)coolitbox
