What JDiskReport is

JDiskReport is a free desktop utility that analyzes disk drives and shows how files and folders use storage. It collects disk statistics and presents them as overview charts and detail tables, helping locate obsolete files and directories. The software runs on Windows, macOS, and Linux; its maker also says it works on Solaris and other Java-enabled operating systems. Java is required. JDiskReport is ad-free, uncrippled, free of charge, and does not expire. Downloads include JDiskReport 2 Beta for Java 8–21 and version 1.4.1 for Java 7/8. Version 1.4.1 is offered as a Windows 32-bit installer, Mac OS X download, ZIP archive, or Java Web Start option. The stable preview of JDiskReport 2 can run as a background cron job, but that preview omits some features, including clicking in the size pie chart. JGoodies describes itself as a privately held company focused on Java product development, consulting, and design.
