JEFview

JEFview... Janome Embroidery Machines (e. g. the MC350E) use a proprietary file format for patterns. Most machines are able to preview these files, but sometimes you want to check them directly at your computer without the hassle of transfering.

JEFview previews JEF files directly on your Mac! As a Quick Look plugin it integrates seamlessly into the Finder's Cover Flow, Spotlight and every Quick Look enabled application like Apple's Mail.
