Many beatmaps I have played before now have now sound at all. When i played them they had sound and when i re-download then they still have no sound. This applies to all gamemodes but mostly to mania. Is there a way I can delete all maps that have no sound from my sounds folder? Or I am I able to get the sound back somehow?I was thinking of making a powershell script to delete all folders that dont contain an mp3 file, but I'm not sure if songs can use other file formats.
