NoteWorthy Composer saves scores as NWC files, while many notation programs and score libraries accept compressed MusicXML files with the MXL extension. Converting the score makes it easier to exchange and edit notation in software that supports MusicXML.
What the NWC format is
NWC is the native score format of NoteWorthy Composer, a Windows notation program. It stores editable musical notation and is commonly encountered in scores created or shared by NoteWorthy Composer users.
What the MXL format is
MXL is a compressed form of MusicXML, a notation-exchange format supported by many score editors. It packages the score’s MusicXML data in a smaller file, which is useful for sharing and opening the notation in compatible programs.
