Files with reserved device names (LPTx, COMx, PRN, etc.) exist on your LAN Manager disk volumes. They cause problems when you are setting access privileges or creating backups, but you cannot get rid of them using File Manager and/or standard commands such as DEL.


These filenames usually are created when an application opens a file instead of a device.


You can't remove these files using OS/2, but you can delete them using an MS-DOS workstation and the QBASIC interpreter from MS-DOS 5.0 or later.

Command sequence:

   net use z: \\<server>\<share>     ; Share the appropriate
  z:                    ; Select default drive
  cd <path>               ; Select appropriate location
  qbasic               ; Start QBASIC from MS-DOS
  enter : kill "z:<file>"     ; Enter this line in the
  select : shift + f5          ; Start execution of the code

This deletes <file> from the shared location.

Repeat this command for each file with a reserved name.
