title: Saving files using Paperclip without upload
body: <p>I had a quick question. Is it possible to save a file without actually uploading it through a form? </p>
  
  <p>For example, let's say I'm looking at attachments from emails, and I want to save them using a paperclip. How do I do this? Do I manually have to call a save_file(or something similar) somewhere?</p>
  
  <p>Any help would be much appreciated!</p>
