macOS - duplicate OneDrive file storage
The files in my macOS (Sequoia 15.6.1, M2 MacBook Air, Microsoft 365 Family) OneDrive folder at /Users/XXX/Library/CloudStorage/OneDrive-Personal/ use 111 GB of hard drive space. The exact same files appear in /Users/XXX/Library/Group Containers/UBF8T346G9.OneDriveStandaloneSuite/OneDrive.noindex/OneDrive/, consuming another 111 GB of storage space. Is this really the case, and if so, WHY? Could one set of files just be APFS clones, and if so, how to verify this? The Finder as well as apps GrandPerspective and OmniDiskSweeper seem to suggest that both groups of identical files are consuming real hard drive space. Thoughts?
