TDP Drive x-Ray


Novell Product(s) this tool is for: any version of NetWare with
NSS or traditional FS

Visual tool for finding and freeing disk space. It's designed to handle large disks with millions of files easily.

Have you ever wondered where your 500GB of disk space has gone to? How many times did you open your favorite file manager or Windows Explorer and browse through all the folders, trying to find some big old file to delete?

Forget it! You can use Drive x-Ray to recover your lost disk space really fast.

Drive x-Ray uses sunburst graph to effectively visualize disk space utilisation of entire disk at once. Sunburst graph is like pie chart, but slices in sunburst graph can have subslices. Slices in sunburst graph represent files or direcotries, subslices represent subdirectories or files found in parent slice (directory). Size of slices represents size of file/directory contents relative to other files in the graph. Largest files cover largest area of screen and are most visible. Slices
are colored so that two adjacent slices have different color.

x-Ray can display contents of selected location in two modes proportional and top-ten. The size of slice in proportional mode is relative to all other files/directories. In top-ten mode, only ten
largest files/ directories are displayed as subslices in each directory. This is useful if there is large number of files with similar size, because x-Ray only displays files that exceed certain computed size threshold. You can switch between proportional (default) mode and top-ten mode using T key.


  • sunburst graph of disk usage on selected logical drive or in directory

  • see largest files/directories instantly

  • optimized for large drives with millions of files

  • graph is sorted by file/directory size

  • drill into directory structure to see details of disk space usage

  • explore directories (using Windows Explorer), open files or file properties directly from graph

  • recycle/delete files or directories directly from graph

  • quickly locate desired directory,drive or network share using tree browser

  • specify network UNC paths/local directories from command line or Dekstop shortcuts

  • quick access to recycle bin cleanup

  • optionally registers as Explorer extension with command 'x-Ray It!' for fast drive/directory inspection

  • fast HW accelerated anti-aliased rendering of sunburst graph

  • opens last 'x-rayed' location when started without parameters

  • proportional and top-ten graph mode

  • full screen mode for maximum screen estate usage

  • quick graphical preview of directory structure of node under cursor

    (small sunburst graph around cursor)

Basic instructions

Use menu on the left to select from available local drives. You can
also use Browse command in the right menu to select location from tree
browser or to enter network UNC path. Drive x-Ray will scan contents of
selected location for file and directory information and update the
graph in the center immediately. Reading of entire disk structure can
take a while, especially on large or slower disks. Information about
name, size and modification time of file or directory under mouse cursor
is displayed instantly in a popup box near cursor.

Mouse navigation

Left click on directory slice to display it's contents.

Double left click on file slice to open file in default application.

Right click on slice to display contextual menu with available commands

Roll mouse wheel to navigate the disk structure (forward go into
directory under cursor, back return to parent directory)

  • decent graphics card with OpenGL acceleration and enough display
    memory (64MB or more) if not sure, try the demo version first

  • memory usage is proportional to the number of files on inspected
    drive (for 100 GB drive with 100000 files around 15MB of memory is

  • disk requirements are minimal (around 300KB) we want to free your
    disk space not to eat it

  • MS Windows 2000 SP4 or Windows XP SP1 is a new version with minor bug fixes and rendering performance improvements.
