Understanding the space capacity and usage of the hard drive is difficult for most folks to grasp hold of and understand. To help with this dilemma I use a small utility (that is FREE) called TreeSIZE Free.
What I especially like about TreeSIZE is that it gives you a visual reference of your directory (or folder) sizes to determine where the real space hogs are. This is especially helpful in making you understand the difference between gigabytes, megabytes and kilobytes. When you first run TreeSIZE, be advised that it will perform an initial scan of your hard drive (or other media) which will take up to a minute or more.
TreeSIZE Free can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders. You can expand this folder in Explorer-like style and you will see the size of every subfolder. All results can also be drilled down to the file level. Scanning is done in a thread, so you can already see results while TreeSize Free is working. The Explorer context menu is supported within TreeSize, as well as the usual drag & drop operation.
TreeSIZE Free is available as a normal setup or as a portable app; AND will run on Windows 7 (32 Bit / 64 Bit), Windows Vista (32 Bit / 64 Bit), Windows XP (32 Bit / 64 Bit), Windows Server 2008 R2 (64 Bit), Windows Server 2008 (32 Bit / 64 Bit), AND Windows Server 2003
(32 Bit / 64 Bit).
