think about changing file system structure to a tree

[jorinvo]

Right now the file system is a flat structure.
This makes some operations easier. And it makes other more difficult.
The biggest issue is that the user can create a structure with holes. If the file system is not connected anymore, it's not really possible to navigate, it's broken.
Also a tree might be easier for the user to create.
Have to see how difficult it would be...
