What is an SFW file?
An SFW file is a compressed image format created by Seattle FilmWorks, a now-defunct photo processing company (1980s–2000s). It was used to store digitized film scans (often from 35mm negatives/slides) and distributed on CDs to customers. SFW uses a proprietary, lossy compression — similar to early JPEG — and often requires their custom viewer to open.
