Opening GP3 files
Did your computer fail to open a GP3 file? We explain what GP3 files are and recommend software that we know can open or convert 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.
The Harmony Assistant, Posix, KGuitar, Guitar Pro OS X, Guitar Pro and Guitar Pro Linux are all applications that can import GP3 files for use with the applications.
Software that will open, convert or fix GP3 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.
