Actually, all of them are "the file": You need all the .ino files in one folder, which needs to be named after the base name of the main file. In this case, when you go to https://github.com/afarhan/ubitx4, you will see that the main file is ubitx_v4.3_code.ino, which means that all these files need to be in a folder named ubitx_v4.3_code
How do I know that this is the main project file? Because it is the only one that contains the setup() and loop() functions. They are an integral part of an Arduino "sketch".
