Does anyone have advice about converting Documents to Files as part of a transition to Lightning?  Magic Mover appears to handle Attachments and Notes, but not Documents.  I'm not seeing anything in the app exchange that does this.

I'm also interested in hearing about tools other than Magic Mover.

This post references using FileExporter to export the files: https://success.salesforce.com/answers?id=9063A000000eHsfQAE
