5 Free Tools To List Hard Drive Contents Graphically

Finding which folders are taking the largest space on the hard drive is an annoying job. I am compiling a few tools here which can help you see the hard drive contents in a graphical and easy to understand manner. In this way you can better organize your hard drive stuff and keep it clean.



OverDisk is a great little tool that can show the hard drive contents in the way they’re placed on the hard drive. Every folder can be shown like this. You just have to select the folder and a graphical implementation of that folder will be shown. It’s still in it beta version.

WinDirStat is a popular disk space organizer and cleaner tool. It reads the whole directory tree once and then presents it in three useful views:

  • The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size.
  • The treemap, which shows the whole contents of the directory tree straight away.
  • The extension list, which serves as a legend and shows statistics about the file types.

SpaceSniffer is the latest of the finds and gives an idea of how the drive contents are structured on the drive.

Start a scan process and see the overall situation. Bigger are the elements on the view, bigger are folders and files on your disk. You need more detail on a big folder? Just single click on it. The selected element will be detailed with its content.

Need more and more detail? Keep selecting elements and they’ll discover their secrets to you. Need a larger view of a small folder? Then double click on it, and it’ll zoom to the full extent of the view.

Xinorbis is a simple but powerful hard disk analyser. Using a sophisticated mix of graphs, tables and tree displays, it gives the user a complete overview of the contents of a hard disk (or directory). It makes it easy to see the contents, structure and file distribution and file composition of a whole hard disk, directory, or mapped network drive. Includes full report creation.

HDGraph is a tool allowing to graphically display the hard disk space usage. It shows all the directories and subdirectories of the hard drive on a single graph, allowing to see the largest directories at a glance.

Note: I have already written about SpaceMonger which also displays the hard drive contents in a graphical way but it’s not free.
