How To Remove Files with Reserved Names such as LPT1 or PRN


Files are sometimes created with illegal or reserved names. The reserved names
follow.

CON, AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN,
NUL

If you have ever tried to delete a file with a reserved name, it is not
normally possible to do so with the del command. NT comes with Posix utilities
including rm.exe which is the unix version of delete. NTFS will not allow NT
native utilities to delete or rename files with the reserved names. NTFS will
allow Posix utilities to do so.

For the file named lpt1:

rm lpt1

If you are uncomfortable with Posix utilities, you can delete such
files using the del command, if you fool NTFS into not doing reserve-word
checking:

DEL \\.\c:\somedir\lpt1

Almost as ugly a syntax as used in file URLs.
