Disk Inventory X is a disk usage utility for Mac OS X (10.3). It shows the sizes of files and folders in a special graphical way called "treemaps".

If you've ever wondered were all your disk space has gone, Disk Inventory X will help you to answer this question.

Please refer to http://www.cs.umd.edu/hcil/treemap-history/index.shtml for further information about treemaps.

System Requirements
Disk Inventory X requires a computer running Mac OS X 10.3 (or newer).

Installation
Just run (double click) the app from this disk image or copy it anywhere you like (the preferred place for applications on Mac OS X is /Applications or ~/Applications).

Quick Start
Open the "File" menu and select "Open Folder...". Select any folder or volume which you would like to analyze. A window should open stating "Loading bla bla". Please be patient if you have selected a large folder or a whole volume with lots of files and folders.
After the loading is completed (the progress window has closed) the main window should open where you see on the left half a finder-like view of the selected folder/volume and on the right half a graphical view:

¨

(1) This finder-like view shows the files and folders with their sizes.
(2) The treemap shows the files and folders in a way that should easily made clear which files and folders occupy most of the space. The selection in the finder-like view and the treemap is synchronized. (Please read (4) for the meaning of the different colors.)
(3) Here some information is displayed about the file pointed at in the treemap.
(4) The file type statistic informs about the count of files of a specific type and the sum of their sizes. The list is sorted by size in descending order. Each type has a color which is also used in the treemap (2). The same color is used throughout all opened folders for each type (see below).

Through the "View" menu you can choose whether you would like to view package contents, you can zoom into folders and some more things which should help analyzing the disk usage.

A word on the use of colors
Disk Inventory X has 12 predefined colors which are assigned to the 8 "largest kinds" (the idea behind this is that it's getting harder and harder to distinguish the colors if there are more than 12). 
The rest of the kinds are assigned to the grey color. This color assignment is made across all opened folders (the color assignment is shared) - files of the same kind have the same color in all opened folders. 
So if you load the first folder all 12 colors may be assigned to some kinds (if the folder contains files of at least 12 different kinds). If you now open a second folder with totally different file kinds, there are no more colors left and all kinds of the second folder are assigned to the grey color. 
The only way to reset the assignments is currently to restart DIX.

Have fun!
