FTP to Dynamics CRM

I am having issues with creating integration map for FTP to Dynamics. I want to grab a file that is created at random times, upsert the contact or account and also set the CRM owner to specific. Lastly, I have a field that exists on the account entity I would like set to a particular account.  Is there a basic map I can use? Also, what do you do for Dropbox or skype for business connectors that don't work with scribe online?  I keep getting a message I need classic. Thanks again.
