What type of files are these?

Ok I have two file types, and I believe that they are c++ 3d images, but Googleing them doesn’t work, cant find anything on them, well one of them I can but the other I just cant. Thought maybe I could get some insight on them! Ok the file types will be below, I will show the file type and just an example like a file name with it, hope you can help!

Unknown file types:

.GSGB File

EX: h_f1_l1_club1_iron.gsgb

.GUI File

EX: GPG_Avatarshop.GUI

I will upload them, so if anyone wants to look go right ahead!
