What is a SPG file?
The .spg file extension is most commonly associated with the TCP Optimizer computer restoration application. The SPG files contain a backup of a user's computer configuration and network settings.
The .spg file extension is also used for Sprint Glossary files and MOIRA text files.

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
