DELETE DEVICE devicename [name [filesystem]]

OS2.0+ only !
* Has the same effect as "FORMAT DRIVE device NAME name QUICK NOICONS".
  devicename is something like DF0: etc., but better not DH0: !
  The name and the filesystem of the disk will be kept the same, except
  you specify new ones. See  INFO  on how filesystems look like.
eg.: You have an Oldfilesystem- (OFS) disk and want to get a Fastfilesystem-
    (FFS) disk out of it. No need to format the whole disk ! Use
        delete device df0: empty ffs
