Created a folder, delete the Text "New Folder" and press alt + 0160 or alt + 255 (Press the NUM keys)
The folder without Name is created...
But here comes the strange,
You cant delete the folder which you have created :)
Here is the step to delete that folder:
That file has a name, even if you can't see it. Open a Command Prompt
window (cmd.exe). At the prompt, type: dir /x
That should show you all the files and folders in that directory. The one
that you named (alt + 0160) should appear with no name in the normal list of
files, but the column before that should show it as "0A00~1". That is the
Short File Name, also known as the SFN or the 8.3 filename. Now use RD to
remove that:
rd 0a00~1
