The filesystem can be directly accessed through "/dev/fs".

There are several IOS functions for FS like Delete/Create/List/Rename/.. .

Files can be directly opened with IOS_Open("/tmp/data.bin",1);



The root folder looks like that:

/tmp

/meta

/import

/shared2

/shared1

/title

/ticket

/sys

Currently, under the Twilight Hack, we are only able to access /shared2 and the /title folder for the running game, and some contents of /title/00010002 (Wii Hxxx channels).
