Efax (apparently not related to Unix Efax, which is strange) is a fax application that runs on MSWindows (but not Unix) and converts the common fax format to their (probably proprietary) format, xxx.efx. Is there any reasonable way to convert an .efx file to a Unix-readable format? To my knowledge, no source code is available, and, when I investigated getting a copy of their code for this limited purpose they were not interested. sam
