First, we are checking for 2 Registry Keys. They are used to recognize the platform a game was installed with.

• Registry Key for Steam (r"SOFTWARE\Valve\Steam")
• Registry Key for Epic Games (r"SOFTWARE\WOW6432Node\Epic Games\EpicGamesLauncher")

After determining your Epic & Steam Library, we check for existence of Files in any given SavePath we know. This way we avoid scanning & analyzing unrelated files and also remove a lot of overhead.
