G1 and G2 without mods writes saved games into the Saves sub-folder, for example: D:\Games\Gothic\Saves.
For a game with mods the sub-folder name for the saved games is formed from a Saves_ prefix and the name of the mod INI file. For example, if the Diccuric mod was installed, in the game folder there will be a D:\Games\Gothic\System\diccuric.ini file. Respectively, the sub-folder for the saved games of this mod will be D:\Games\Gothic\Saves_diccuric.
I repeat for the last time: G1 and G2 don't save their games in a personal user profiles. Therefore, if you have an empty Saves folder, so you have nothing to transfer. Everything is clear now, Morra?
