Disksum

This is a little program I wrote to find out what takes the most space on my hard drive.

There are prettier pieces of software like one called treesize but I like mine anyway.

It's something like the UNIX "du" program but with sorting by size.

It will tell you:

• which folders have lots of files in them (this is a hidden performance suck for filesystems)
• which folders use lots of storage
