I am wanting to save individual project files to my USB memory stick just in case of PC failure/ theft / baby sick and other unexpected events. I've assumed the file I need is the reaper project file within the song folders however this file is only a few hundred KB which got me thinking it's something else?. I basically want all the track elements and settings of a song saving so I could load a new version of reaper up in the future and add an old song to work on with all the song components in place.
