/VFCSIZE=size Sets a new value for the VFC size in the file
    header. This value will only be used with the VFC record type.
    2 SPAWN Spawns a subprocess. 2 UNDELETE The Undelete command
    recovers deleted files. It is done as safely as possible. If
    undelete discovers that the file header or blocks of the deleted
    file have been reused, the undelete process will stop. The
    /FILE, /IDENTIFIER or /OWNER qualifier can be used to select
    specific files. The /LIST qualifier can be used to generate a
    list of recoverable files without actually undeleting files. If a
    matching filename is found undelete will ask for a confirmation
    before undeleting the file. Multiple files can be undeleted with
    just one UNDELETE command. After a successful undelete the file
    will be entered in the original directory if possible or in
    the [SYSLOST] directory. NOTE: The volume (set) will be locked
    for other users during the undelete command unless the /LIST
    qualifier is used. Syntax:
