JDiskReport enables you to understand how much space the files and directories consume on your disk drives, and it helps you find obsolete files and folders. The tool analyses your disk drives and collects several statistics which you can view as overview charts and details tables.

DiskReport provides different perspectives about your disk drives: absolute and relative sizes, size distribution, distribution of modification dates, and distribution of types.

Each perspective includes a pie chart, a bar chart, and a details table. You can choose to either show the file size or the number of files. Also, JDiskReport collects a list of 100 largest, oldest, and newest files.
