Hi, you can retrieve a list of media assets if that helps you. This contains the names of all events, Master-Mixer-Hierarchy, Actor-Mixer-Hierarchy etc. but not the names of the original files that are used when playing a container.
In your Wwise project go to Project - Project Settings - SoundBanks and activate "Generate Bank Content TXT Files". You will find the file in your Bank path. Hope that can help you.
