The plugin can calculate and show every part of the disk usage of projects (jobs, workspaces, builds...), but it is limited to items type projects. But other items like pipelines, multibranch pipelines, folders, etc. are not applicable to this plugin. We need a new release that includes displaying disk usage for every item in Jenkins in the UI item view. 

This feature may help users with limited access to view their current usage, change their job settings to achieve the best performance, and remove unused data if necessary. 

Thanks in advance
