What is JDiskReport?
JDiskReport turns disk-usage statistics into charts and detailed tables so you can see where storage is being used. It is useful when you need to understand which directories occupy space and identify files or folders worth reviewing. The publisher describes it as ad-free, no-charge software that does not expire.
The linked Windows package is JDiskReport 1.4.1, listed by JGoodies as a 32-bit installer for Java 7/8. Install Java before installing JDiskReport. The publisher also offers a separate JDiskReport 2 beta; that beta's Java requirements and features should not be assumed to apply to this package. Exact Windows build support is not specified on the cited pages, and this entry does not claim installation testing on Windows 10 or 11.
