Recommended practices when using a Shared/FTP Drive on the servers containing the Primary and Secondary Availibility Groups?

Hello, we are currently using 2, 2014 SQL Server Enterprise Servers that contain our AlwaysOn High Availability groups. 

Server One is the primary replica ,

Server 2 is the secondary replica, not being used for read-only. 

In the event of a failover, what is the best recommended practices to automate the secondary server's connection to a Shared/FTP drive that is used daily by the Primary Server?

I apologize in advance if this is the wrong forum for this question.  I realize it is Windows Explorer related as well, however, I was assuming some of the users of AlwaysOn High Availability Groups may already have a solution in place that works. 

Thanks.
