I have an 8TB model, and it says I have 1.3TB of free space, but when I go to Windows Explorer or use Treesize I can’t see where the space is being used. I’m pretty sure I don’t have over 6TB of files on it.
I’ve drilled down into each folder and can’t see any files or folders taking up this much space.
In Treesize the top level says “2.1TB”, but at the bottom it says “Free Space: 1.24TB of 7.06TB”.
