Display most likely desired 'next' sector (in hierarchy) in default format
This will display the 'next likely' sector on the current opened store
by using the 'next' value set by any previous display of a sector.
Displaying the 'next' sector (Ctrl+N) on an opened filesystem will
show the most interesting sectors like bootsector, superblocks etc.
In general, each display function will set this 'next' value to the
sector that is the most 'desirable' to be visited/displayed next.

Open a logfile for all screen output to come, append if file exists
This will present a 'file-save-as' dialog with a suggested
filename in the current directory. You can change the name
and navigate to other volumes, directories and even create
a new directory for the logfile.
All information that goes to the screen will be appended
to the specified file as well.
When the specified filename in the dialog ends in a '^' character,
the program will automatically number new logfiles sequentially, by
appending '001' .. '999' to that filename, and selecting the first
one that does NOT exist yet (see automatic logfile numbering).
When the specified filename in the dialog ends in a '~' character,
the program will replace that by a DATE string in the form YYYYMMDD
(see automatic logfile DATE postfix)
DATE/TIME format substitution
-----------------------------
The filename may contain date/time format strings, substitued as:
~1 Day 2 digits (DD)
~2 Month 2 digits (MM)
~3 Year 4 digits (YYYY)
~4 Hour 2 digits (HH)
~5 Minute 2 digits (MM)
~6 Second 2 digits (SS)
~7 Full name of current weekday
~8 Full name of current month
~9 2 digits ISO 8601 weeknumber

Functional trace program-flow to 9 one-MB cyclic files, for DFSee debugging
This will present a 'file-save-as' dialog with a suggested
filename in the current directory. You can change the name
and navigate to other volumes, directories and even create
a new directory for the tracefiles.
Functional tracing will be enabled, and logging will be set
to use three files of maximum 1 Mb in size, so the risk of
filling up the available space is greatly reduced.
The first file will have file extension 'log' and the rest
will use a number extension '.lnn' with nn being the logfile
sequence number starting at 01 and without an upper limit.
This method of tracing is intended to allow analysis of
crashes (traps, access violations) in DFSee itself that
are very hard to diagnose otherwise.

On selection this will open a 'file-open' dialog listing the
RAW or COMPRESSED imagefiles present in the current directory.
The file-dialog has controls to let you change the volume,
directory and selection-wildcard to allow easy selection
of any file accessible through a drive-letter.
Selecting one of these will open it for further use and display
the first sector of the imagefile.
This is most useful to open PARTITION imagefiles, containing a
filesystem, that can then be BRWOSED, or analysed on other ways
Using BROWSE, you can selectively COPY files from a compressed
partition image (.IMZ), making these a good alternative for
other backup solutions.

MemDisk from .PDx Template ...
From main menu: File -> Attach/Detach/Display disks -> Attach to DFSee disk-list -> MemDisk from .PDx Template ...
This will present a file-open dialog where a .PDx file
containing saved disk-information can be selected.
On selecting such a file, the new virtual disk will be
created with equal size and geometry, and the saved sectors
from the .PDx file will be loaded into the virtual disk.
When matching .SNx/.BNx or .IMx files are present, these will
be imported or restored to the new virtual disk automatically.
This is extremely useful to create a virtual copy of an
existing disk for partitioning or recovery experiments.
The results of the DFSDISK script are ideal candidates to
be used as templates for a new virtual disk (DFSDISK?.*)
A VIRTUAL disk only exists within memory in DFSee, and can be
used to analyse a setup or test many partitioning and recovery
scenarios without any risk of damaging the real disk.
Note: Since the whole virtual disk is kept in main memory, some
commands like WIPE, CLONE and imaging are not practical to
use on them, they would fill all available memory ...

Empty virtual disk
From main menu: File -> Attach/Detach/Display disks -> Attach to DFSee disk-list -> Empty virtual disk
This will present a dialog where the size of of the new virtual
can be specified using either CHS-geometry based values or a
direct size in binary megabytes or gigabytes (MiB/GiB).
The default for the size unit is MiB. Example values:
800 ;will create an 800 Mib virtual
117,g ;will create an 117 GiB virtual
3748,c ;3748 cylinder disk, default geometry
3748,c 128 32 ;3748 cylinders, 128 heads, 32 sectors
When left blank, the disk will be modelled after the currently
selected disk, with the same size and geometry.
The virtual disk will be completely empty after creation.
A VIRTUAL disk only exists within memory in DFSee, and can be
used to analyse a setup or test many partitioning and recovery
scenarios without any risk of damaging the real disk.

containing a partitioned disk image can be selected.
On selecting such a file, the RAW image will be opened and
attached as a new partionable medium.
This means the contents will be shown with the 'part' command
and all other DFSee functionality for disks and partitions is
available for the image ...
This is extremely useful to analyse or work on RAW container
files for virtual-machine products like SVISTA or Virtual Box.

VirtualBox diskimage (*.VDI) present in the current directory.
The file-dialog has controls to let you change the volume,
directory and selection-wildcard to allow easy selection
of any file accessible through a drive-letter.
For a VBox BASE VDI, this will add it as a new DISK, from
which you can select a partition, and start a BROWSE session.
For a (matching) SNAPSHOT VDI, it will automatically ADD this
to the corresponding BASE VDI disk. To add a complete virtual
disk, you should first open the BASE VDI, then all snapshots
in the correct order, oldest to newest.
When a snapshot VDI selected does NOT match any of the already
opened BASE VDI disks, it will be opened as if it was a BASE

Detach from DFSee disk-list
From main menu: File -> Attach/Detach/Display disks -> Detach from DFSee disk-list
This will remove the selected 'disk' from the list of partionable media.
Partionable media, known as 'disks' within DFSee, can be listed using
the 'media' command or the menu-item 'View -> Partionable Media'.
Every item listed is considered a 'disk' so its partitions can
be displayed, analysed and worked on.
The DETACH action will remove one 'disk' from that list, making it
unavailable for other DFSee functions until you attach it again.
By default, at DFSee startup all physical disks will be attached,
and on exit all disks will be detached automatially.
