Disk Usage Analyzer is a graphical application for analysing storage device usage. It can be used to scan multiple local or remote storage devices, including hard disks, SSDs, USB sticks, digital cameras and memory cards. Disk Usage Analyzer can scan either the whole file system, your Home directory, a specified folder or a remote directory.

The results may be useful in deciding which folders can be archived, deleted or moved to free up space. You can also use the results to estimate how much space would be needed for a backup of specific folders.
