Tip for organzing you emulators folder make top level folders for manufacturers or type of game so for Example you have Nintendo then inside you have your Dolphin your Cemu Citra Desmume. Then for Arcades you can have a top level and put MAME FBA Demul Sega Model 2 emulator Super Model TaitoTX Nesica Teknoparrot. Emulators usually don't take up much space so organzing them further may be a better solution than just jettisoning them completely.
