KDE

In my experience mtp (especially on Linux) stops working if you look at it wrong, so probably not.

Haha, that may be, I've never done anything aside from just moving and copying files with it luckily, so I don't really know.

Perhaps kde connect’s folder view works?

Interesting idea, I should try that!

I’d run gdu in termux on the phone though.

Ooo, you just unlocked a fabulous CLI tool for me that I didn't know about!
Does it work on the whole phone storage? I remember there being a symlink (?) to the user's home in Termux's folder, but I'm wondering if it'll leave something out
