Tools that scans disk and find biggest N directories. Useful to clean disks.
I know that the same could be achieved with unix command line:
du -h <DIR> | sort -h -r | head -n 30
But this tool is multi-platform, shows progress, use less memory and display results on Ctrl-C.
When compiled or downloaded JAR could be used as following:
java -jar diskbiggest-1.0.jar . 30
