Let's assume I have a bundle which weights like 100mb, and it might be updated on server. If it gets updated, a client re-downloads it (using WWW.LoadFromCacheOrDownload with a new version number). After a client finishes downloading, it knows for certain that previous version will no be longer needed and it can delete it (otherwise it will consume that 100mb for Caching.expirationDelay seconds). I can't set expiration delay to some low number since it will affect other bundles as well. Is there any way to delete it without deleting ALL the cache using Caching.CleanCache?
