LibDsk is a library intended to give transparent access to floppy drives and to the "disc image files" used by emulators to represent floppy drives. It currently supports the following disc image formats: - Raw "dd if=foo of=bar" images; - Raw images in logical filesystem order; - CPCEMU-format .DSK images (normal and extended); - CFI-format disc images, as produced by FDCOPY.COM; - ApriDisk-format disc images; - NanoWasp-format disc images, used by the eponymous emulator; - Yaze 'ydsk' disc images, created by the 'yaze' emulators; - Disc images created by Teledisk and CopyQM (read only); - The floppy drive under Linux.
