EF3 to MIF Conversion: FAQ

What are EF3 files?

EF3 is a format associated with fax machines manufactured by Everex under the Everfax brand, which was fairly popular in the late 1980s. EF3 files contain images of sent and received documents and might be difficult to open using regular image viewers. Everex was well known as a manufacturer of tape drives, graphic boards, DTP products and other computer devices throughout the 1980s, but its success decreased in time. After filing for bankruptcy, the company was acquired by New Market Technology in 2008 and now continues to produce desktop computers and notebooks.

What are MIF files?

The MIF extension can be associated with vector images under the MapInfo Interchange Format, in which case it consists of a map and a database exporting file. Also MIF or MIFF file format represents a raster image associated with ImageMagick.
