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.

Find deleted/normal files, list and possibly recover them. HEX edit dir/file
This submenu offers selections to search for normal or deleted
files, display the resulting lists and possibly recover files.
It also offers selections to HEX-edit either the meta-information
for a file (DIR-entry) or the actual file contents

Search for deleted (or renamed) files ('Recover from list' NOT POSSIBLE YET)
This will search the whole partition for DIR-entries of DELETED
files that match the partial filename (wildcard) specified.
The sectornumbers of the found DIR-entries will be added to the DFSee
sectorlist so can be used in later actions, or be exported to a file.
The files contained in that list can NOT be RECOVERED yet, due to the
missing or incomplete allocation information for deleted files on EFAT.
RECOVER will be unreliable by definition, but there might be some
'best-we-can-do' type of recovery offered in future versions ...

Search data area for non-deleted files/directories, for 'Recover from list'
This will search the whole partition for DIR-entries of non-deleted
regular files that match the partial filename (wildcard) specified.
You can also search for specific file-extensions by using a syntax
like '*.ext' or '*.c*' for the partial filename
The sectornumbers of the found Dir-entries will be added to the DFSee
sectorlist so can be used in later actions, or be exported to a file.
The files contained in that list can be RECOVERED to any directory
on the system, including a network, by using the 'RECOVER' command.

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.
The dialog will allow 'actions' to be performed on the listed
files/directories, using <ENTER> to get the popup menu:
- View contents, as ASCII on File/Dir
- View as x86 Assembler - disassembly
- HEX-edit, contents only on File/Dir
- Edit Contents, autoview on File/Dir
- View OS/2 EA or Xattr on a File/Dir
- Edit DATA area sectors for File/Dir
- Edit META:Inode/Fnode/MFT/Dir-entry
- Edit the base filename for File/Dir
- Copy/Recover File(s) to other drive
- Reduce list to SELECTED files only
When the browse session is ended (<Esc> or <F3> key):
- the SAME filesystem/partition stays selected
You can restart browse the same partition with the <F9> key,
or start browsing another partition from the Actions menu
using: 'Actions -> Open Partition, Browse FS'
- the sector-list contains the last browsed directory
and can be viewed with commands like 'list -f
- The last entry (file) that was selected will also be set
as the current sector-location ('this'), so it easy to
analyse that furthher, for example by using the HEX-editor
that can be started with <F2>, or simply by viewing the
sector using the <Enter> key.
Note: When working in 'mode=FDISK' (with a whole disk opened)
you will be presented with a selection-list to pick a
partition with a filesystem first.

Display (selected) files from the list, using a PATH+FILENAME wildcard
This will display the DFSee sector-list in a compact format, suited
to the data contained in the list
This usually is a 'list -f' or a 'list -s' variant.

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).

Find info (FNODE/MFT-record etc) for ONE specified file/directory path
This uses the specified path from the root-directory to locate
detailed information for the file or directory for that path.
This will be from the FNODE on HPFS, the MFT-record on NTFS or
similar structures like Inodes on other filesystrems.
The path and filename may contain spaces.
When found the information will be displayed in the standard
format as defined for the filesystem that is active.
You can display related information like the directory entry
or the actual file data from there using the U and D commands.
You can also use the 'saveto' command or corresponding menu
item 'Recover THIS file' to create a copy of this found file
on the specified or default recovery destination
(or use the combined menu option instead of this find :-)

Press <F1> again for more help; Some options may require switching to 'Expert mode'
Find ONE file by full path+filename, and recover it to a recovery directory
This uses the specified path starting from the ROOT to locate
ONE specific file, and when found will issue a SAVETO command
to recover the contents of this file to a recovery directory.
The path and filename may contain spaces.
Note:
The recovered file will be placed directly in the specified
recovery directory without the full original path, but with
the proper filename retained (even on JFS :-).

Find + edit FAT dir entry / HPFS fnode / JFS inode / NTFS MFTrec+small files
This uses the specified path from the root-directory to locate
information for the file or directory for that path.
This will be from the FNODE on HPFS, the MFT-record on NTFS or
similar structures like Inodes on other filesystrems.
The path and filename may contain spaces.
When found the information at THAT level (1st, direct)
will be opened in the standard HEX editor
This will often be META-data about the file or directory,
with a layout strongly defined by the filesystem type

Find, then HEX edit most HPFS / JFS / NTFS file-data or directory contents
This uses the specified path from the root-directory to locate
information for the file or directory for that path.
This will be from the FNODE on HPFS, the MFT-record on NTFS or
similar structures like Inodes on other filesystrems.
The path and filename may contain spaces.
When found the information at the NEXT level (2nd, indirect)
will be opened in the standard HEX editor
This 'next' level is what would be displayed using a 'd' command
or using the ENTER key when the first level is being displayed.
It will often be data or contents for the file or directory.

Display/Edit Volume info like label, Serial-nr and dirty/clean status
This submenu offers several selections to Display or Edit
Volume properties like label, serial-number and dirty/clean status
The label is an 11-character string, in the ROOT directory
The volume serial number should be a unique value in the system
The file system status can be one of:
- Clean When it is not in use, proper shutdown
- Dirty When in use, and changes have been made
In some cases, when CHKDSK fails, you can get (temporary) access
by manually setting the FS status to Unmounted-clean and reboot.

Display/Edit the standard 11-character label (in bootsector and ROOT DIR)
This will present a small dialog to display and/or edit the
standard (DIR) label, with a maximum length of 11-characters
and located in the ROOT directory
This standard label is used to identify the filesystem in
commands like DIR and FORMAT

Change the volume serial number, making this volume unique (after clone :-)
This will update the 'volume serial number' in the bootsector
This could be REQUIRED for some operating systems after cloning
a filesystem, to make sure the volume serial numbers are unique.

Update EFAT status in BOTH bootsector areas to indicate filesystem is CLEAN
This will update the fileystem-status field in the EFAT bootsector
to indicate that filesystem is CLEAN.
The primary (LSN 0..11) and SPARE boot area (LSN 12..23) are updated.
This can be useful to avoid an automatic CHKDSK after a system-crash
Note: The filesystem itself is NOT cleaned in any way, it is just the
statusflag that is modified.

Fix bootsector area (LSN 0..11) by replacing it from spare area (LSN 12..23)
This will repair a broken EFAT bootsector (area) by replacing it
with the spare-copy found at LSN 12 (0xC).
This can be very useful when the bootsector got damaged by a virus
or a crashing program (writing to sector 0) or if the partition was
deleted by accident using FDISK or LVM and recreated again.
The menu item is implemented using the 'bootsync -s' command, and
in that process it will also recalculate the boot-area CRC values.

Press <F1> again for more help; Some options may require switching to 'Expert mode'
Fix CRC for bootsector area (LSN 0..11) then sync to spare area (LSN 12..23)
This will recalculate the boot-area CRC value (sectors LSN 0..11)
and also copy those to the spare-copy location at LSN 12 (0xC).
This can be very useful when the bootsector has been edited manually.
The menu item is implemented using the 'bootsync' command.

Wipe the Bootsector, FIRST sector in a filesystem. Remove obsolete FS info
This will wipe the bootsector (first sector) of the selected
filesystem or partition.
Can be useful to get rid of old formatting infomation
that may confuse tools when trying to reformat.

Reset the bad-sector administration to show ZERO bad-sectors or clusters
This will check for bad-sectors being present in the
filesystem and when present, reset to NO bad sectors.
FAT: Reset all 'BAD' values in the FAT to FREE
EFAT: Reset all 'BAD' values in the FAT to FREE
NTFS: Update $BadClus and $BitMap to reset bad-clusters
HPFS: Make the bad-sector-list in the spare-block empty
This can be very useful after cloning or imaging a partition
or disk that includes bad-sectors to a new replacement one.

Find and list possible EFAT Rootdirectory (using bitmap/upcase entries)
This will try to find directory-sectors that would qualify as a
valid root-directory (dir-sector with BITMAP/UPCASE system files).
This can be useful if the root-directory reference in the EFAT
was damaged and is not recoverable in another way (fixboot).

Make the currently selected PRIMARY the 'active' partition for MBR/BIOS boot
This will make the currently selected PRIMARY partition the
ACTIVE one for the disk.
There should only be a single active partition on every disk.
When the system starts, the BIOS will usually boot from
the ACTIVE partition on the first disk.
In IBM BMGR/LVM terms the active partition is called STARTABLE.

Delete the currently selected partition from the partition tables
This will delete the partition that is currently selected to be
deleted from the partition-tables. This will result in the space
occupied by the partition becoming FREESPACE that can be used
again to create new partitions.
For primary partitions on LVM-systems, the related LVM-information
is cleared as well, to avoid consistency problems later when a new
partition is created at the same position.

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!

Press <F1> again for more help; Some options may require switching to 'Expert mode'
Show identification for specified (or current) sector, using the SLT
This will display information about the specified sector that is
available in the sector lookup table (SLT)
The most useful info is the sector referencing this sector, this
often leads to showing to which file/directory the sector belongs.
The SLT will be generated automatically if not yet available

Press <F1> again for more help; Some options may require switching to 'Expert mode'
Show identification for the last sector used, dictating the minimum FS size
This will display information about the sector that is the last
one being used (allocated) in the filesystem, and because of that
dictates the MINIMUM size for the filesystem for a RESIZE.
The most useful info is the sector referencing this sector, this
often leads to showing to which file/directory the sector belongs.
The SLT will be generated automatically if not yet available,
just as the required allocation information (alloc).

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
