Project update sync process

Client sync process option A (Client driven)

---

Benefits

• Lower memory use as we are working on a file by file basis rather than holding lists

Drawbacks

• Needs multiple client file passes to sync everything

Client sync process option B (Server driven)

---

Gist

• The client starts a sync process with the server
• The server sends a series of questions to the client asking if it has various files
• The client deletes any remaining files

Benefits

• Single sync process, only need to fetch the clients files once

Drawbacks

• Relatively complicated dialog between the client and server for file sync

Could potentially combine both approaches and do an early delete phase to get rid of client files that don't exist on the server.
