A folder inside a folder.
No arch. Where the arch was, a small folder is cut in, standing on the bottom edge: once on its own, once with its own parent edge, so the mark holds itself.

Which one
The same folder four ways: a small folder inside, a layered one inside, nothing inside, or nothing inside with a bigger curve.
B · Layered folder, as the mark
The inside is exactly the outside: a layered folder holding a layered folder. That is the inception, and it reads at a glance from 32 px up.
At 24 and 16 px the parent edges drop away and it becomes a folder holding a folder.
A or C, if B feels busy
A keeps the folder inside without the extra edge. C drops the inside altogether: the boldest, and the easiest to reproduce.
