If you do not have SUN's Java Runtime Environment installed, download and install Java v1.3.x or later.

Extract jdu.exe.jar to any location (for example "My Documents" or "Desktop"). Double click to run.


This is a simple program. First click on "browse" and select any folder/directory on your computer (larger folders will take a longer time to load). Next click on any of the folders to view their children. Click the folder on the very left to go "up" one level.

Right click for options and the about box.

Most operations do not require reloading directories.


Designed and tested on Windows NT. Results on other OS's may vary. Specifically symbolicly-linked directories may cause UI problems and the UI in general is not well tuned to the Motif look & feel.

OutOfMemoryErrors are recoverable, just don't try to read that directory again.

Folder text does not wrap (yet).


If you get an OutOfMemoryError, then try running jdu.bat, or for the more experienced add "-Xmx=256" to your command line, where "256" is the MB of memory you will give the application.
