I can’t believe Microsoft is still using this piece of crap filesystem. If they had a CoW filesystem they could even paper over the mess that is Windows Update without having to actually fix it, they could save petabytes of storage over the world and significantly improve reliability all in one go. Let’s not even mention how NTFS is amazingly slow on hard drives, manages to fragment to hell and back without doing anything, requires offline repairs like it was FAT32 and its compression barely does anything while massively slowing down the computer.

Yet here I am envying btrfs, APFS, ZFS and even fucking XFS for their reflinks and CoW.

In fact, not even WSL uses a modern FS, I think Microsoft is allergic to modern FSs.
