Disk Inventory X - Disk Usage Utility

This application allows you to view the size of files and folders on your hard drive in a graphical manner. Once scanned the contents of one or more of your disk drives (including removable drives) is shown in various sized blocks which are colour coded in relation to their file type.

This method of display can make it easy to track down large files or folders that you could delete to free up some much needed hard disk space. You can use the browser to delete files from within the application or open Finder windows to browse the directory.

This application is derived from a Linux utility called KDirStat. As such there are almost identical versions for Linux and Windows.
