Try to create a folder in Windows with either of these names--
"con" or "nul" or "Aux" or "Lpt1".
Windows will not let u create ....
Reason: all this correspond to some of the famous ports
>con corresponds to the console
>Lpt1 corresponds to printer and so on....
HOWEVER I FOUND A TRICK TO CREAT FOLDER "CON"
Here is a simple method..........
Rename folder from the right click option........
Now press alt and press 255...
press 255 frm the right sideof the key bords i.e., num pad....
where only numbers r given.....
now write con and then press enter.....huh!!
you ll see a con folder in ur pc
and also you can delete it easily
