Your ISP offers you 30MB of disk space, but doesn't tell you how much space is used. This tool enables you to get a usage piechart from your FTP service, showing which directories are taking the most space, and to drill down into those directories to see which are the largest files. Simply double-click on a pie segment to drill down.
You will see the program working to retrieve your Web space usage details. Please note that the site name and directory details will be different for your ISP. Once the program has finished, a pie-chart like the one below will be displayed, and you can double-click on a directory to drill down and see its contents. This makes it very easy to clear out the maximum space with the minimum effort.
