StupidFax File Viewer

StupidFax File Viewer is a tiny and portable application you can use to open and view APF fax files, as well as to convert them to common image formats that can be opened by regular graphic viewers.
It features simple and intuitive options that can be tackled by users with any experience level. APF-formatted files are created by fax-oriented software products, such as APRO, Mighty Fax, Fax2000 and Snappy Fax.

Portable tool with a clear-cut GUI

The entire program's packed in just one file that can be copied to the hard disk or a removable storage unit (like a USB flash drive), in order to directly run the .exe on a machine without any previous setup. It doesn't need any DLLs to run or change Windows registry settings. However, it creates a CFG file in the same location as itself, in order to store your configuration settings on exit.
It's wrapped in a seemingly outdated interface that doesn't put any emphasis on the graphical elements. However, it's easy to navigate, thanks to approachable options.

Open and convert APF fax files

It asks you to begin by specifying the output directory for saving all converted files. Afterward, you can use the file browser to open an APF file and view its graphical contents, zoom in and out, or change the page orientation by rotating the image to any angle by 90 degrees.
Furthermore, it's possible to compress whitespace, copy selected parts of the picture to the Clipboard, print everything, as well as convert the fax file to BMP, PCX, DCX or TIFF filetype. The default destination directory for the new files can be modified anytime.

Evaluation and conclusion

It worked smoothly in our tests, without causing the OS to hang, crash or show error dialogs. CPU and RAM usage was minimal. Thanks to its intuitive GUI and options, StupidFax File Viewer can be handled by anyone looking to open APF fax files and convert them to more user-friendly graphic file extensions.
