The CPCEMU disc image format (conventional extension .DSK) is conventionally used for images of Amstrad CPC, Amstrad PCW, and Spectrum +3 [[floppy disk]]s.

It is thus the ''de facto'' disc image format for most 3" [[floppy disk]]s. (There's probably no technical reason it couldn't image other disk types, but typically it doesn't.)

Such disk images will often (but not always) contain a [[CP/M file system]].
