DriveSort sorts the directory tables of a volume formated in FAT12/FAT16/FAT32. This sort orders the files in each folder according to their short or long names alphabetic order. The majority of recent operating systems sort the files before showing them to the user, either by name, by size or by whatever the user choose. However, it is not always the case in embedded OSes on small portable devices like MP3 players. On these platforms, the lack of resources (CPU, memory) can lead the developper to make it display or play the files in the order in which they are on the disk. This order depends mostly of the order in which they were added to the disk. DriveSort can change this order to help such devices to play or view their files in the order you want, by putting them on the disk in a customizable order.
