The best option available to reduce hosting storage space

Media Cleaner is the only option I know of that can scan my site and find unused media that can be deleted to save storage space on server. I wish I knew this was available sooner as it is a great solution. You do have to be careful that it does not delete images that are in page builders, but I found that the Pro version does a great job of resolving that issue. The free version should be good with Classic or Gutenburg.
