Visual Disk Diet helps you visualize the space used on your drives with a colorful radial tree chart.
Now you can see quickly which folders take so much space, and get rid of them (coming soon).
Coded with java/processing.
Feel free to use, modify or suggest ideas!
It's pretty much a copy of Disk Space Fan but Open Source so it can be adapted to extended purposes (as browsing file system...)
It's very fast on data drives (your data partition, usb drive...)
It's NOT optimized for very large and complex drives such as big C: drive for now so it can take up to 10 minutes to scan it (and there is no feedback during this scan, so it can be frustrating).
