Thank you! Nice to know I’m not crazy :-)

Regarding windows. Does NTFS support this? Like COW and other advanced stuff? Or am I doomed if the underlying FS is NTFS?

At work I have to use windows (11) and i always have the feeling file-related stuff (copying, moving, doing stuff in large git repos) takes a loong time compared to my own devices thst run linux with btrfs.

Now that you’ve got the idea apply it to everything in capitalist society. Especially if something is owned by shareholders.
