This is the solution of this problemSeveral special file names are reserved by the system and cannot be used for files or folders, these are:
CON, AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL
These are special keywords used in DOS and their use may accidentally cause problems with your system... here are their keyword de******ions;
CON Keyboard and display
PRN System list device, usually a parallel port
AUX Auxiliary device, usually a serial port
CLOCK$ System real-time clock
NUL Bit-bucket device
A:-Z Drive letters
COM1 First serial communications port
COM2 Second serial communications port
COM3 Third serial communications port
COM4 Fourth serial communications port
LPT1 First parallel printer port
LPT2 Second parallel printer port
LPT3 Third parallel printer port
These are called short file names. Short file names have the 8.3 format and are compatible with MS-DOS and other legacy operating systems. They allow the windows OS to communicate with DOS or basically give the OS the ability to access files on a volume. Playing with these file names and creating garbage
folders, may cause your system to crash
