Why you not simply use a VFAT partition? It's the most backward compatible, long name capable filesystem for TOS programs what don't really support enhanced filesystems like ext2fs or minix.
Frank, you're genius, thanks! I'm working probably too much in the unix environment ;-)
Btw Evil, if you're reading this, why didn't you do this? The same reason? (i.e. you didn't notice the possibility of VFAT use)
