Mode=ISO Menu: [ISO9660 CDROM/DVD .iso image File System]

Select Volume Descriptor

Select active volume descriptor including its Directory-treee etc. from list

   This will present a submenu with all identified Volume Descriptors
   in the filesystem, so you can select one for further use.

   There usually are several Volume Descriptors in an ISO9660 FS
   and the most common are:

        Type 0:    Boot descriptor, boot mechanism like El Torito

        Type 1:    Primary descriptor, standard UPPERCASE names

        Type 2:    Supplemental descriptor, often 'Joliet' to allow
                   long filenames and lowercase characters

   The selected descriptor (vdi) determines which directory tree is
   used by DFSee for function like BROWSE.

   After opening a filesystem, a default Volume Descriptor will be used,
   the first type-2 (Joliet) when present, and otherwise the first type-1

Reselect whole disk, FDISK

Unselect filesystem, reselect the same/first disk; enables Mode=FDISK menu

    This will UNSELECT the current object/filesystem, and reselect a
    whole physical disk, either the same disk as the partition was on,
    or the first disk present in other cases.

    This is a quick way to change to 'Mode=FDISK' and work on
    disk-level issues
