Backup structure

Within the target folder, for every game with data to back up, a subfolder will be created based on the game's name, where some invalid characters are replaced by _. In rare cases, if the whole name is invalid characters, then it will be renamed to ludusavi-renamed-<ENCODED_NAME>.
Within each game's subfolder, there will be a mapping.yaml file that Ludusavi needs to identify the game.

When using the simple backup format, there will be some drive folders (e.g., drive-C on Windows or drive-0 on Linux and Mac) containing the backup files, matching the normal file locations on your computer. When using the zip backup format, there will be zip files instead.
If the game has save data in the registry and you are using Windows, then the game's subfolder will also contain a registry.yaml file (or it will be placed in each backup's zip file). If you are using Steam and Proton instead of Windows, then the Proton *.reg files will be backed up along with the other game files instead.

During a restore, Ludusavi only considers folders with a mapping.yaml file.
