I have mentioned before on here the definitive document from Microsoft. Search their site for a file called fatgen102.pdf. The 102 is the revision of the file, and so may change, but IIRC the last time I looked for it I just searched for "fatgen". This file is the definitive definition of the FAT file system, and contains all sorts C code scraps on how to do the various operations, and also details the pitfalls of some other implementations that are around, and why they can fail. -- http://www.piclist.com#nomail Going offline?
