What is a SFW file
Bitmap images with a SFW file extension have been created with the, by now, outdated application Seattle FilmWorks which was used for film processing. Some programs are still able to view SFW files even though files with this extension use a proprietary format. Seattle FilmWorks and PhotoWorks have been discontinued.
The SFW file format is actually an MGI PhotoSuite file and a raster image file. This file extension is also captured by IrfanView, Graphics Converter Pro and others.
Here's a small, but not exhaustive list of programs that can open SFW documents:
- SFW PhotoWorks
- American Greetings SFW & PWP File Converter
