Mode=HFS Menu: [Apple MAC HFS+ journaled File System]

Allocation map display

From main menu: Mode=HFS -> Allocation map display

Display a pseudo-graphical map of used versus free sectors in the filesystem

Menu item screenshot(s)


    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.

Set Volume info/status

From main menu: Mode=HFS -> Set Volume info/status

Display/Edit Volume info like label


    This submenu offers several selections to Display or Edit 
    Volume properties like the volume label

    The label is a 255-character string, present in several nodes
    of the Catalog Btree structure

Set Standard Volume Label

From main menu: Mode=HFS -> Set Volume info/status -> Set Standard Volume Label

Display/Edit the 255-character volume label located in the Catalog file tree


    This will present a small dialog to display and/or edit the
    standard volume label, with a maximum length of 255-characters
    and located in the Catalog file

    This standard label is used to identify the filesystem in
    commands like LS and FORMAT, and in the Finder application

    The actual label value is present in several of the Catalog Btree
    nodes, since it is by definition a Key-value. DFSee will update
    each of those nodes when changing the label string.

    The maximum allowed length may be limited due to the available
    space in all of the nodes to be updated.

    NOTE: Setting the label requires WRITE access to the volume!

          You can get that using the macOS DFSee version using:

          File ->
             Device and Volume management ->
                Unmount volumes from a disk ->
                   ... select the disk holding this volume ...

Delete THIS partition

From main menu: Mode=HFS -> Delete THIS partition

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.

Display Catalog info

From main menu: Mode=HFS -> Display Catalog info

Display Catalog information, for specied or pre-defined Nodes or Folders


    This submenu offers several selections to Display contents from
    the Catalog file, which holds directory-like information for all
    files and directories (folders) in the filesystem.
    Both Directory-like display formats as more in-dept Hex-dumps
    are available to allow analysis of the Catalog contents.

    The info to be displayed can be restricted to single folders by
    specyfing a folder-id (also called CnID), or it can work on the
    entire Catalog file.

   Display directory information for any folder, given a folder-mumber
   also known as CnID, specified in a hexadecimal number format

   It will walk the chain of all leaf-nodes and display the entries that
   are related to the specified folder-number, and describe either file
   or folder information.

Fldr-0, ALL folders/files

From main menu: Mode=HFS -> Display Catalog info -> Fldr-0, ALL folders/files

FOLDER 0, ALL folders/files in the filesystem, could be millions of lines!


   Display directory-style information on ALL folders/files in the filesystem
   with date and time, attributes, file/resource size and the file/foldername

   It will walk the chain of all leaf-nodes and display all records that
   hold information on folders or files (it skips the 'thread' records).

   Since it does NOT display housekeeping information about each node visited,
   the displayed list is a sorted list of folder and file names (plus info)
   that is grouped by parent-folder number, and sorted alphabetically.
   WARNING: Since this displays information about ALL folder/files, it may
   take a long time to complete, and show millions of lines of output

        You can use the <Esc> key at any time to abort!

FOLDER 2, The ROOT directory for volume, can navigate from listed entries


   FOLDER 2, the ROOT directory for volume, you can navigate from listed entries
   by selecting a line with the .NNN command, whic will display information on
   the file or folder shown on that line.

   For example, if the shown line starts with '.0000023', the DFSee command:

                .23
   will display the information related to that line. If it was a folder,
   it will show the contents of that folder.
