My spotify is taking up a lot of space and I'm not sure of it's just the app or if it could be me downloading songs for offline play. Either way I want to delete some files but I don't know what they are or how they might affect me. Any advice?
The most likely culprit will be the offline files for your songs, especially if you have them set to download as high quality. To delete them you'll need to go to your playlists and simply thin out how many you have set to be availible offline. Once you've done that restart whatever device you're using and you should notice a reducation in the amount of space Spotify is using.
