Many of you might be knowing this trick to make a folder without any name (except a space as the name) in windows Xp. Any ways, here let me tell about it once more.
Just make sure that you have nums lock on.
Then go to the folder which you want to rename with no name at all, then, right click it and select rename and then clear its contents.
Then press and hold the ALT key and then type 0160 in the Num pad. Now release the ALT key.
Press enter.
Now you will be able to see that the folder has a space as the folder name.
The trick accounts for files as well.
