Audio file storage

[brianstoiber]

I have been running a podcast site for about 3 years and use the PowerPress WordPress plugin. Looking at my server usage, I see that the storage size has grown substantially and I am trying to find an answer or solution.

I host all the audio files on AWS so I thought they were only stored there. However, when I look at the wp-content\uploads\peaks\ directory, which I believe is being created by this plugin, I see that there are 3 files for each audio file. There is an INFO, PEAKS, and MP3 Audio File. The first two I am not worried about as they are each 13KB combined and are what I believe to be creating the waveform. The audio file is what concerns me as it is the actual audio file already stored on AWS. This has made the directory grow to 14+ GB.

• Are these audio files required to be here?
• Can I delete them?
• Is there a way to stop them from being stored on the site and only be stored on AWS?
