Today I faced a peculiar issue, where I was trying to create a file named
It was a short code file and needed to be named with this name only.
The issue in this name is that PRN is a reserved keyword in the CMD execution shell.
Thus the file cannot be renamed to PRN.<extn> where <extn> can be any extension.
Do not use the following reserved device names for the name of a file:
CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, PRN, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names followed immediately by an extension; for example, NUL.txt is not recommended
