Global file-name characters are not permitted in the name of the file to be deleted.

Read-only files cannot be deleted by DosDelete. To delete a read-only file, you must first issue DosSetFileInfo to change the file's read-only attribute to zero, then delete the file.

If a storage directory for the drive has been defined with the SET DELDIR command, the UNDELETE command may recover the deleted file.

DosDelete cannot be used to delete directories. Issue DosDeleteDir to delete a directory.
