Have you ever gone through your diskettes or hard disk subdirectories to weed out obsolete or unwanted files? It is easy enough to use the “?” and “*” wildcard characters to delete files with common elements in their names or extensions, using commands like “ERASE *.BAK” or “ERASE RESULT?.DAT” but, if you want to delete a group of files without common elements to their names, you have to issue a separate ERASE command for each one. Until now!
