Hmmm... You're right of course. I didn't describe that well. I meant Unix file names and way of working with files vs. Windows. In other words, forward slashes, symlinks, mounts, sane permissions, etc. I hate dealing with drive letters, etc. What's a good name for this?

Oh, the UX of the file space layout.

NTFS/Windows actually has all of that stuff you want, too. NTFS's permission system, for example, is extremely feature-full and integrates nicely with the user system (ACL support by default rather than an add-on, for example). The octal user-group-all permission you're probably used to is pretty crude by comparison.

It's more likely just you're unfamiliar with it rather than it's actually missing anything.

But if you want you can just pretend C:\ is equivalent to / and mount all your other drives at C:\mnt\whatever, that's completely doable (with a GUI to configure it if you want, even)

Agreed. NTFS is one of the few things I missed.

I’m still annoyed that APFS doesn’t have file level checksums.
