I've recently become confused about which is the current file for my mmex. Every time I open the application, it loads a file and then seems to add to the name and save it under a new name? My "current" version is "EOB2014.mmb_start_2014-01-24.mmb_start_2014-02-11.mmb_start_2014-03-14.mmb"! Can you refer me to an explanation of this procedure, and how I might just work on one file all the time? It gets saved to a backup, so I don't really need these multiple files. I currently have about 6 MB of these variously names files!
