This Redmine 4 plugin stores file attachments on Amazon S3 instead of the local filesystem.

!!! Actually, I don't like this solution, but it works for me and it was fast implementation ...

-> Much more I would appreciate if Redmine switch to Active Storage which is part of Rails and works like a charm for locals storage end even for cloud storages.
