Most of what you can do with this is take the structures that FAT offers you and transform them to other, smaller or faster, structures that contain the same information. If you can make a smaller or faster structure, why not store it? This way, you both need to derive them time and time again (slowing stuff down needlessly) and/or you need to cache / buffer them in full (making your FS library eat memory). That seems very wasteful. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
