Cakewalk Project (CWP)

Cakewalk by Twelve Tone Systems (later Cakewalk, and now Roland) saves project data including MIDI data, project settings, and pointers to audio files, in a project file of the CWP format. A "bundled" version including the audio and other files too is called Cakewalk Bundle (CWB). Older versions used the WRK project format instead, with the BUN format for bundles.

Other Cakewalk file formats:
 * Cakewalk Dump Request Macro (.drm)
 * Cakewalk Instrument Definition File (.ins)
 * Cakewalk Sample Definition File (.sfz)
