•this is a time saving feature for clean-up tasks and compacting your project
•unlock it by going to the Inspector Mode drop-down menu in the taskbar
•switch from Standard to Advanced
•then access the Delete Options from the Project Explorer's context menu
The two options are self-explanatory:
- delete specific content and all of its versions from all connected discs.
-only delete unused versions of selected content from all connected discs.
This will affect also source files on source systems. If you have a project with multiple systems, please keep in mind that only active & connected systems will have that content deleted. Once that information is gone with the deleted file, systems re-connected thereafter will not be able to perform that task again.
