Folderity is a fast and lightweight music player for Windows that allows users to create custom playlists in folders on their computer that automatically update when a song is added or removed from the folder. This is very convenient for anyone who has a large collection of music files (MP3's, WAV's, etc.), since it allows the user to automatically organize their music into playlists without having to manually add songs to the playlist one at a time.
Folderity is programmed in C++ and uses Microsoft Media Foundation (MMF) for the audio playing component. MMF is rather complex to use, so to simplify its use, I created a helper library called MMFSoundPlayer to help programmers with quickly being able to play audio files in their C++ programs.
