SFWJPG - Seattle Filmworks to JPG conversion (Windows)
SFWJPG - Convert Seattle Filmworks .SFW files to .JPG.
SFWJPG is a Win32 port of the UNIX hosted application written by Everett Lipman.
It may be used freely according to the GNU General Public License.
The ZIP file in the download link below includes the Win32 command line executable and 'C++' source code.
The April 2016 update adds support for Seattle Filmworks 93A format (SFW93A). Thanks extended here to Helmut Jurgensen for providing sample 93A content and to Richard Jones for a great write-up on SFW file formats and the differences of 93A vs. 94A.
Retain your source imagesWhile digging through the internals of the 93A files, I observe additional data that has not yet been pulled into the output file including the date the film was developed (SFW93A and SFW94A). If I can figure out how to map this into the jpg header, that would be a good addition to the program and considering fixes made earlier to undo mirroring in SFW94A files, it is a good idea to retain the original image files even after conversion.
Execution requirements:Program requires Windows version Vista or beyond (e.g. Vista, Windows 7, 8, 8.1, 10 and 11).

From a graphical user interface, this will appear as a flash.

This question comes up often, I have created a video to show the process.

To convert many files, place all .SFW files into a single directory.
For example a SFW folder under "Pictures".
Using command prompt, change directory (CD) to the directory that holds pictures, then "SFWJPG *.SFW".
The program will create a .JPG for each SFW file that is processed and place that JPG in the same directory.
