DiskSCOUT is a diskmonitor, diskspace analyzer, disk scan utility, treesize explorer, watchdisk tool. But unlike most other diskmonitors, DiskSCOUT is not designed to find large folders or files, but to mark those where changes in size have occurred between scans. DiskSCOUT is especially designed to track the historical development of your hard disk space usage from past to present. You may scan your disk once an hour, once a day or once a week - everything is saved into a database and changes per folder can be displayed over a range of time periods. DiskSCOUT is very easy to use and will show you in a user-friendly-way when and whereto your disk space has disappeared over time.
