A .spf file is a Still Picture Interchange File Format (version 1.0). This one is a specialist format without an obvious everyday home.
How to open a .spf file

- On Windows, use a hex viewer or the free TrID tool to identify what the file really is.
- On Mac or Linux, running `file yourfile` in the terminal identifies most formats instantly.
