It wish we could have talked about it a bit before it was commited.. Most of ffs_rawread.c is fairly generic. Do you think you could make a vfs_direct.c or similar and move the generic bits in there? It looks like you could keep the ffs specific bits to a minimum and then leave the rest as helper functions. Do you have an application that is using this immediately? Cheers, Jeffhelp
