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
/shared1
/ticket
/sys
For a more detailed example of how the file system structure can look, see http://www.openwii.org/forums/viewtopic.php?p=1241#1241.
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). Zelda also has access to some game-saves, depending on the permission flags set by the game.
