Missing Disk Cleanup Button

When selecting "Properties" after right clicking a disc name (e.g C:) there used to be an option to perform a Disc Cleanup such as empting Recycle Bin etc. There is only a "Details" button now. Has Disc Cleanup/Empty Recycle Bin been moved elsewhere or is it no longer available? I am using Directory Opus Pro 12.30 Build 8360 x64. Thank You

The Properties dialog comes from Windows, and should have identical options if you open it on the same drive within File Explorer.

Did you try holding down the Shift key, while right clicking? You will get an extended menu then, with maybe the missing function.
