EF3 to DIS 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 DIS files?

The DIS extension is associated with the DKB Ray-Tracer, a piece of software originally created by David Kirk Buck and Aaron A. Collins, which served as a predecessor for the POV Ray-Tracer. The latter software has the capacity to generate images from text-based scene descriptions and works on various platforms. Though fairly popular on PC/MS-DOS platforms at its release, the DIS format is now obsolete. It can, however, be viewed and converted to more accessible formats.
