Users often use up available disk space on a system as quickly as you add it. If you want to track your disk space usage, try Micro Logic's DiskMapper.

Unlike other utilization reporting tools, DiskMapper creates a color-coded map of your disk to illustrate where users are consuming the most space. This information helps you determine which files to delete (i.e., files that are consuming a lot of space) and which files to copy to offline storage (i.e., files your users don't use).
