Disk Space Manager scans directory structures and stores the sizes of each directory. These stored sizes provide a historical snapshot of your server's disk space usage on a directory by directory basis. Comparing current sizes to previous sizes allows you to very quickly see which directories have grown and project future disk capacity needs. Disk Space Manager intelligent sorting, simple drill-down user interface, and reports make it easy to quickly find the information you need. Naturally low disk space alerts haven't been forgotten. But Disk Space Manager goes one step further: Besides just alerting on low disk space, it can alert you on significant changes in disk space usage as well.
