Hello @NoahO, I'd like to point out that enabling sharing between Mac and Windows has nothing to do with disk space or linked clones. Mac files/folders appearing in Windows due to sharing being enabled are simply reflections of actual files/folders and are not real/tangible data that need extra disk space.
Are you referring to the option 'Configure' under Options -> Sharing in the VM configuration window?
Could you kindly describe the exact issue in Windows you are trying to convey by this statement?
Additionally, the error message seen in the screenshot you have provided only occurs when trying to enable sharing when 'None' is selected for 'Share Folders' in the same screen. Please let us know how this relates to your query.
