I originally had a Downloads folder, but decided to create a separate partition for it.
So I renamed Downloads to Downloads2. I know, I should have just cut and pasted the content, but this seemed easier.
Anyway: for some reason Downloads2 was now the default Downloads directory. It even got the Ubuntu Download icon (the arrow alone)
But no matter what I do now: Downloads2 is still the default download directory. Even changing its name does nothing this time around. How is that possible? And how do I change it?
