PhotoWorks (Image Conversion/Pictures on Disk Software) wrote:Overview
We started offering Pictures on Disk in 1994, at which time PhotoWorks was know as “Seattle FilmWorks.” Image files on our Pictures on Disk from 1994 to mid 2001 were provided in a proprietary file format with the .SFW file extension. Because the SFW file format is not a standardized file format, most photo applications will not open these files. You have probably reached this page because you have some of these files which you are trying to figure out what to do with.
We still offer free software for download that will allow you to view your SFW image files and convert them to standard file formats such as JPEG so that you can open them in other applications. This software will also allow you to open PWP files (archives containing several SFW image files which we used to offer for download on our Web site). However, the software was last updated in the year 2000.
Because we stopped providing SFW images on our disks several years ago, there are no plans to release future updates to our software for opening these files. We recommend that you use the software available now to convert all of your SFW image files to a standard file format for archiving purposes because our software will not likely work on future operating systems such as Windows Vista.
See below for information about the legacy Pictures on Disk software that we offer for download as well as links to third party applications which provide support for the proprietary SFW image file format.
The last release of our Windows Pictures on Disk software for opening SFW files was PhotoWorks version 2.41, released in 2000. PhotoWorks 2.41 was originally developed for Windows 95, 98 and NT 4.0. However, the software will also operate fine under Windows 2000, Windows Me and Windows XP.

This version of our software includes support for importing and exporting many standard image file formats including JPEG (.JPG), Windows Bitmap (.BMP) and TIFF (.TIF). It also includes a batch conversion feature that makes it easy to convert large groups of photos.
3rd Party Solutions
Below is a list of third party applications that provide support for the SFW image file format under Windows:
Developer: Pierre.e Gougelet
Web address: http://perso.wanadoo.fr/pierre.g/xnview/enhome.html
Notes: XnView is free, easy to use and supports both SFW and PWP file formats.

Everett Lipman (File format conversion software for Seattle FilmWorks products » details.txt) wrote:A .pwp file consists of a group of .sfw files (typically all of the pictures from a roll of film) which have had some additional information prepended to them (such as the file name and length).
pwpjpg reads the length and file name information, and then passes each .sfw file to the same routine used in sfwjpg, which converts the file to JFIF and writes it to disk.
Everett Lipman (File format conversion software for Seattle FilmWorks products » usage.txt) wrote:pwpjpg will take a .pwp file and extract the images in the file. A .pwp file typically contains the scanned images from an entire roll of film. The names of the images are contained within the .pwp file. pwpjpg takes a single argument, the name of the .pwp file from which to extract the images:
pwpjpg mypics.pwpThis will extract all of the images contained in mypics.pwp and write them in the current directory as .jpg (JFIF) files. The file names will correspond to the names of the images stored in the .pwp file. mypics.pwp will not be altered or removed. Under Microsoft Windows, pwpjpg.exe must be invoked from the run window command line.
Joe Nord (SFWJPG — Seattle Filmworks to JPG conversion (Windows)) wrote:FAQ #1:
A couple users have noted that after downloading and executing the program, all they see is a flash.
SFWJPG is a command line executable. If you run it from graphical user interface, the program will lauch, display help text and then terminate. From a graphical user interface, this will appear as a flash.
The program should be run from a command line. (Start / Run) then "cmd" <enter>.
Execute sfwjpg program from command line with no parameters to get information on required parameters.
Some other folks have noted that the program does not support wildcards. This is true and adding this support would be a worthy enhancement — but it has not been done. To work around, execute this command at the Command Prompt. This procedure assumes that all SFW files are in the current directory when program is run.
for %F in (*.sfw) do sfwjpg %FThis will execute sfwjpg.exe once for each SFW file in the current directory. With the output filename omitted, the program creates the output file with the same name as the input file with the extension changed to ".JPG".
Bengt Cyrén (Free Seattle FilmWorks image converter) wrote:SFW2JPG.EXE is a small MS-DOS utility that will convert Seattle FilmWorks image files to plain vanilla JPEGs without reducing the already limited quality. Usage is straightforward. Bring up a MS-DOS box, go to your SFWs and type:
SFW2JPG *.SFWYour original SFWs will not be overwritten. The program can also convert a single file or convert files between drives etc. If SFW2JPG.EXE is launched without parameters, it will display a brief help text.

- XnView home.
- XnView is a software family to view, convert, organize, and edit graphic and video files.
- Converts .sfw and .pwp files.
- Binary available for Windows, Linux, MacOSX.
Also available for Android, iPad/iPhone, etc.
- Is an extremely usable GUI, yet includes a command line interface.
- Can do batch converts, both in the GUI and from the command line.
- Has many features.
- Available in a portable version.
- It costs $0 for "private non-commercial or educational use (including non-profit organization)".
- I highly recommend it (even though it is not open source).
- Even photoworks.com recommended it, as can be seen on the latest Internet Archive's record of the photoworks.com "Image Conversion/Pictures on Disk Software" page circa 2007-05-13. The photoworks.com site suggested XnView as one of two 3rd party alternatives to the Seattle FilmWorks / PhotoWorks v1.0.1 software that ran on Classic Mac computers (and did not do batch converts).
And it was additionally recommended as a 3rd party alternative for the PhotoWorks v2.41 software for Windows.
- To see the .sfw and .pwp files, you might need to check "Display all image file types" in Tools / Options / General / Operations, then click OK.
- Can extract all the .sfw photos in a .pwp file -- contrary to some of the comments in this XnView newsgroup thread -- using the Tools / Multipage file / Extract All Into function. However, XnView will not preserve the filenames like Lipman's / Nord's sfwjpg will do. Instead, it creates .sfw files with filespecs using the filename of the .pwp file appended with "_page_nnn.sfw", where nnn is the sequence that XnView encountered the .sfw file inside the .pwp file. After XnView does the Extract All Into, you can rename the files to your liking.
- Can be used to examine a file in hex -- as long as the file format doesn't choke XnView. Simply select the file, then click Tools / View in Hex mode. So, if no other tools are available to detect the SFW98A or Uncompressed SFW94A formats, you can manually do that with XnView.
- XnView is intelligent enough to display a file with filetype .jpg that is actually a SFW format file. And, vice versa, it will display a file with filetype .sfw that is actually a JPEG format file.
- It is my present mechanism for visually detecting the quality of original vs. converted images. I simply switch back and forth between the images several times to see which looks better.
- Is my preferred tool for opening a single .sfw file on a PhotoWorks CD then quickly scrolling through all the other .sfw files in that directory. Also, is my preferred tool for opening a .pwp file then quickly scrolling through all the .sfw files inside that .pwp file.
