Venika, I'm not sure what software Ms. Veronica digitizes in, but lots of the programs do not offer the JEF Plus file format yet. I was told the regular JEF format will run on the new Janome machines. But, go ahead and grab the JEF+ format when you do see it. They are gradually changing over.
Could you be a little more detailed. I do not understand the +fil. Is there a certain design you are trying to get?
