Did your computer fail to open a GP3 file? We explain what they are used for and recommend software that we know can open or otherwise handle your .GP3 files.

What is a GP3 file?

Files that contain the .gp3 file extension are usually used by the Guitar Pro 3 software application. Guitar Pro 3 allows for the editing of guitar and bass tablature files and the creation of scores for stringed instruments, such as the bass and the guitar.

The music files that are created and saved by the Guitar Pro 3 software are saved with the .gp3 file extension. While the files contain scores that are used to create music, the files do not contain any actual audio data in and of themselves.
