Hello Aamir and Dinesh Sir,
This is a cool trick to create a folder without any name which is not possible in normal way of folder creation but if you press this "Alt+255". It gets no name and the folder is created without any name. You can try this out.
Well i do agree with Dinesh sir, and really you have given the nice explanation for this trick.
