Rebuild & resync Hub contents with network share: format drive?

I finally have my hub set-up to recognize my network share and had it sync my network shares contents with the hub.  Prior to doing getting the hub to recognize my network share, I had manually copied over some of my network shares files to the hub so I could start using the hub.  Once I got the network share recognized and synced, I ended up with lots of duplicated files.

How do I start over to that I have only the contents of my network share synced with my hub and no files duplicated on the hub?  Should I use the Hub “disk manager” to “reformat” the hub, thus erasing the hub’s content and restart the hub so it will resync the contents of my network share?

That’s probably the FASTEST way…
