Welcome to the SequoiaView Homepage

SequoiaView 1.3 was launched November 2002

 Standard treemaps often lead to thin rectangles. We have developed a new method to display files : Squarified treemaps. The screen is subdivided such that rectangles approach squares as closely as possible. The screenshot gives an example.

Ever wondered why your hard disk is full? Or what directory is taking up most of the space? When using conventional disk browsing tools, such as Windows Explorer, these questions may be hard to answer. With SequoiaView however, they can be answered almost immediately. SequoiaView uses a visualization technique called cushion treemaps to provide you with a single picture of the entire contents of your hard drive. You can use it to locate those large files that you haven't accessed in one year, or to quickly locate the largest picture files on your drive. The screenshots below give a first impression of the original cushion treemaps:
Inspect details of any file on your harddrive
Locate those big files you never use

SequoiaView was developed by the computer science department of the Technische Universiteit Eindhoven and can be downloaded for free from these pages. For more background information click one of the links on the left. Click here to download SequoiaView (approximately 500 Kb).
