File menu
In the first menu item 'file' you will find everything that has to do with the melody as a whole: new, open, save, close, [ [play|play]] and print (see also file manager and folders).
With 'search' you can search your computer for MusiCAD music with specific content.
The last (default 5) lines concern the most recently opened melodies. You can set the number of previous melodies under [Preferences|Files]. The last opened melodies contain any playlists used previously.
A number of preferred locations can be configured in [Options|Locations]
