Opening SP3 files
Did your computer fail to open a SP3 file? We explain what SP3 files are and recommend software that we know can open or convert your SP3 files.
What is a SP3 file?
Files with the .sp3 extension contain Quake 2 Sprite Builder files. These files contain sprites that can be loaded in the Quake 2 gaming application. The SP3 files are stored in the PCX file format, allowing the files to take up less disk space without compromising the quality of the file.
Software that will open, convert or fix SP3 files
Try a universal file viewer
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.
