Redmine

Does anyone know if there is a plugin that allows us to share content/large files with external organisations?

We have Redmine operating within our organisation, however now and then we will need to share a large file with someone that is external to our network (e.g. a customer) and wondered if we can send them a link (from Redmine) to allow them to download a file?

For example if I need to send a 55mb document that is too big to email to a customer?

We previously used Google Drive and/or Dropbox but would be ideal if we can use Redmine somehow?

Cheers
