Hey, guys. I thank who wants to help me with this problem: I want to customize the music of the MODS that I have installed with the GP4Sound tool but I select the path where I want the converted file to be, I select the file to convert, I click on create GP4 file and I The message that the file name is invalid appears. I have tried many combinations and the same message always comes out. What name should I give the file to convert? Is there any other solution?
