Display a pseudo-graphical map of used versus free sectors in the filesystem
Display a usage map for the currently selected disk or filesystem
A pseudo-graphical map of the disk or partition allocation is
displayed, showing the distribution of data over the object
This is also an indication for the amount of unused sectors in
the object, that are beneficial to 'SMART-SECTOR' optimizations
in imaging and cloning operations.
The percentage of used sectors are displayed as a percentage at
the end of the line, and a total usage percentage and size is
shown just after the map itself.
For filesystems that support resizing, the limits for resizing
are shown after the map itself.

Browse files/directories in a list from a single directory, or current list
This will show the contents of a single directory, specified
by a PATH from the ROOT directory, or by selecting a directory
from the browse list itself (including the '..' directory).
Alternatively, the CURRENT contents of the sectorlist can be
browsed, when available (by specifying a '.' for the directory
The list can be browsed in an interactive dialog, a bit like
a regular filemanager.

Recover (selected) files from the list to a supplied recovery directory
This will allow you to recover (copy) one or more of the files in the
list to any local or network directory on your system.
It will prompt for a destination directory first, using the last used
one as a default. All files recovered in one go, will be recovered to
this same directory, with their original path appended to retain the
directory structure whenever possible.
It will also prompt for a selection specification in the form of a
full PATH+FILENAME wildcard and an optional allocation-percentage.
As an example, the specification:
'*mydoc*\*project_x*.doc%100'
will recover all files that have 'mydoc' somewhere in the PATH,
'project_x' in the filename and have an extension of '.doc' that
seem to be 100% recoverable. (100% allocation-OK ranking).

The menu item will only be enabled (selectable) when the CURRENT sector
represents a normal or deleted FILE for the filesystem involved.
This means it has to be a type 'f' or 'z' sector, which is:
For HPFS: an FNODE sector
For JFS: an INODE sector
For NTFS: an MFT record

Update $Volume special file flags to indicate filesystem is in NORMAL state
This will update the fileystem-status field in the NTFS $Volume file
to indicate that filesystem is in a NORMAL state, no CHKDSK required
This can be useful to avoid an automatic CHKDSK after that flag has
been set by a utility (such as DFSee) or by a 'CHKDSK C: /f' or the
corresponding context-menu item for the system volume.
It CANCELS the scheduled CHKDSK that would be done on the next boot.
Note: The filesystem itself is NOT cleaned in any way, it is just the
statusflag in the $Volume special file that is modified.
The clean versus dirty state of the filesystem itself is kept in the
$Logfile special file (journal log) and can not be modified by DFSee
It IS displayed when opening an NTFS partition, or whenever the
DIRTY command is used.

Windows could not start because the following file
is missing or corrupt: Windows\system32\Hal.dll
The specified or calculated value will be substituted for the
partition-index in the default line.
Of course you need to reboot to test if this fix worked ...
Note:
Unless you specify the ' -2' option with the value,
this is NOT a full 'REPAIR' of your BOOT.INI file!
It is just the minimum update to allow booting Windows again!
You must properly edit boot.ini once Windows is running again,
or use 'bootcfg /rebuild' from the recovery-console that can
be started from regular Windows installation CDs.
When there is damage to the BOOT.INI file beyond an incorrect
partition-index, fixing it this way might not be possible.

$MFT special file, Master File Table itself, full allocation
$MFT special file, Master File Table itself, full allocation
Everything on an NTFS volume is a file, and each of those files
is described by its own MFT-record in the Master File table.
An MFT record holds references to all attributes for the file,
where attributes can be 'resident' in the same MFT-record, can
be 'external' in an allocated area of clusters (run-list)
or even can be described in a secondary MFT-record.

$LogFile special file, the NTFS transaction log, used in CHKDSK recovery
$LogFile special file, the NTFS transaction log, used in CHKDSK
This is the transaction log, where all pending changes for the
filesystem structures are kept. This allows very quick recovery
of the filesystem to a known good state after a crash.
Note: User data is NOT kept in the logfile, so after a crash
there CAN be damage to 'open (user) files'. It is just the
filesystem structures that are kept safe using this log!

$BadClus special file, Bad Cluster list using SPARSE file, non-sparse == BAD
$BadClus special file, Bad Cluster list using a SPARSE file
This is a SPARSE file, that normally just has a single extent
representing the whole volume, and is not-allocated (-sparse-).
When bad-clusters are detected, they are added to this file
as allocated areas. Every allocated area is 'BAD' and since it
is now allocated to this special file, it will not be used ...

$Secure special file, index to centralized security info for volume
This is a collection of security information for the volume, which
is indexed by a security-index kept in the 'standard' attribute for

It replaces the 'security-descriptor' attribute that was used in the
older NTFS versions (NT, NTFS 1.2 and older) for efficiency reasons.

$Extend special file, index to more special files: $ObjId, $Quota, $Reparse
$Extend special file, index to more special files (open ended)
This is a regular directory, listing any special files not in the
fixed set, it is used for the added files in NTFS 3.0 and later:
$ObjId = index of all the $OBJECT_ID Attributes on the volume.
Every MFT Record is assigned a unique GUID (starting with W2K).
Additionally, a record may have a Birth Volume Id, a Birth
ObjectId and a Domain Id, all of which are GUIDs.
$Quota = special file storing information about file quotas
In W2K and later this file keeps track of quotas (disk usage).
This is administred PER USER en per volume
$Reparse = special file storing information on reparse points.
A reparse point is like an equivalent of a UNIX symbolic-link.
It 'mounts' a file/directory, a network share or other volume
somewhere in an existing directory structure.
$UsnJrnl = user readable variant of the transaction/recovery log.
It does not seem to be used very often, not seen one yet :-)

Check filesystem for inconsistencies and errors (Readonly, no fixing!)
This will perform a CHECK of the filesystem, somewhat like the
well-known CHKDSK but without automatically fixing anything.
The result of the check is a sector-lookup-table (SLT) that contains
information about all recognized filesystem areas that are in use.
Any error recognized will be flagged in the default display of
this SLT that is performed automatically by the CHECK command.

Create Sector Lookup Table (SLT) if needed, display as table or sector info
This submenu allows you to build and inspect a 'Sector lookup Table'
or SLT, that collects some info about each identifiable sector range
in the currently selected filesystem.
The SLT is the basis required to identify specific sectors, showing
to what file or FS-metadata it belongs, and for the CHECK command.

Show layout of current object by displaying parts of the Sector Lookup Table
This will display part of the sector-lookup-table (SLT)
You wil be presented with an option dialog first, where you
specify the desired format and part of the SLT to be displayed.
The SLT will be built automatically if not done yet, and it will
have been built by any previous CHECK command too.
Building the SLT will take place in the background while the
dialog can be used freely to specify any options for displaying.
After the dialog has been ended, and the SLT is ready, it will
be displayed as requested.
Typically the SLT will contain at least one entry for every file
on the filesystem, so there could be hundreds of thousands lines!
