DiskUsage is a tool to show content of a folder structure in a more graphical manner.
It's inspired by a tool named SequoiaView. And it's also the reason for my experimentation with bumpmapping, which resulted in the implementations included in JavaLib_Common_Imaging.
The tool can read the output of shell command du -a {path} > {file} and uses this format to store tree data in text files (-> "Stored Tree").

DiskUsage includes a subtool named DiskUsageCompare, which is used to compare 2 folders or more precisely to compare 2 states of the same folder. These states can be read from stored folder tree data or can be scanned from HDD.

You can download a release here.
You will need a JAVA 17 VM.

DiskUsage is configured as a Eclipse project.
It depends on following libraries:

• JavaLib_Common_Essentials
• JavaLib_Common_Imaging
• JavaLib_Common_HSColorChooser
• JavaLib_Common_Dialogs

These libraries are imported as "project imports" in Eclipse. If you want to develop for your own and

• you use Eclipse as IDE,
  • then you should clone the projects above too and add them to the same workspace as the DiskUsage project.
• you use another IDE (e.q. VS Code)
  • then you should clone the said projects, build JAR files of them and add the JAR files as libraries.
