The disclosed embodiments relate to a system that facilitates accessing audio files associated with a user from an online content management system. During operation, the online content management system receives a function call from a client to list audio files associated with the user. In response to the function call, the system filters through operations for files associated with the user to identify audio files. Next, the system returns metadata for the identified audio files associated with the user to the client. In some embodiments, filtering through the operations involves filtering an operation log to identify operations performed on audio files associated with the user, wherein the operations occurred since a preceding call to the function.
