TDP x-Ray is a visual tool intended for disk space administration. It has been designed to simplify the work with high-capacity data storage containing millions of files.

You shall appreciate TDP x-Ray, for example, when there is no free space on your 500GB disk and it is not clear where all the free space has gone. Instead of spending hours of your time browsing through folders file by file in the effort to find out what can be removed from the disk, TDP x-Ray shall provide a clear graph showing the disk space occupation. In the graph, you can immediately see which files and folders occupy the most space.

To easily visualize the entire disk space, a special “sunburst” graph is used. In fact, it is a multilevel round diagram. The graph levels correspond with the structure of the selected disk or folder. The size of specific parts represents a relative size of the respective file or folder in comparison with the other files on the disk. The largest files and folders occupy the most space on the screen, which makes them easy to identify. Part colors are selected so that two adjacent colors always differ.


  • Clear round graph displaying the occupation of the space on a disk
  • Large files or folders can be identify immediately
  • Optimized for large disks with millions of files
  • The graph is divided based on the size of files / folders
  • Easy movement within the folder structure of a disk – immediate information about the occupation of a specific part of a disk
  • Possibility to open a file in the Explorer or to view properties directly from a graph
  • Deleting files / moving them into the thrash bin directly from a graph
  • Searching for a file on a local or network disk using the Browse function, which displays the tree structure
  • Launching TDP x-Ray with a parameter, which is the path to a folder on a local or network disk
  • Quick thrash bin emptying directly from the application
  • Possibility to register TDP x-Ray with the Explorer context menu – upon using the 'x-Ray It!' command, TDP x-Ray shall open on the required folder
  • Quick and anti-alias graph views accelerated by hardware
  • Launching TDP x-Ray without parameters shall open a folder viewed last time
  • Proportional and top-ten mode of the graph
  • Full-screen mode
  • Quick review of the structure of a folder below the cursor

HW and SW Requirements

  • Graphic card with OpenGL with a 64MB memory (or more)
  • The memory utilization depends on the number of examined files (for a 100 GB disk with 100,000 files, you need memory of about 15MB)
  • Approximately 500KB of space on a disk for the application + approximately 1 to 10 MB for cache (depending on the number of files on the disk - 10MB corresponds with approximately 180,000 files). You can choose not to use cache (see “Configuration File”)
  • MS Windows 2000 SP4 or Windows XP SP1
