EFX files are associated with Everex Everfax, a type of fax document created by the Everex fax software. This file format was used for storing and sending fax documents electronically, allowing users to manage fax communications directly from their computers. The EFX format contains all the necessary information to accurately reproduce the faxed document, including text and images. Everex Systems was a prominent computer manufacturer and software company during the late 1980s and 1990s, and its Everfax product was among the early solutions integrating fax technology with personal computing.
A BMP file is an uncompressed raster image comprised of a rectangular grid of pixels. It contains a file header (bitmap identifier, file size, width, height, color options, and bitmap data starting point) and bitmap pixels, each with a different color.
