Local files are media stored on your computer. It's important to note that the only local files you can add to your Spotify library are songs. However, Spotify does not support all file types. Spotify accepts files with extensions that include the following: .mp3, .m4a, .m4r, and .m4p. Note: M4P files that include video will not be permitted. File formats that aren't supported (but can get converted on your end) are FLAC files (m4A) and other lossless formats. If you still can't find your local files, ensure you didn't turn on any filters in your playlists. Also, make sure that you are using the correct account. To find a song in your Spotify library, go to the Search bar and type it in. Note: Spotify doesn't allow you to upload local songs or those obtained from illegal sources.
