CIS Scanning to folder setup - Clarification please

Hi

I'm very new to Xerox network scanning and am hoping for a little clarification on the setup process.

I'm looking at setting up scanning for individual members of staff on a WorkCentre 7556.

At the moment there are 4 Templates set up under 'Scan' in Centreware Internet Services (which I'll call CIS if it's ok...).
Each is for a department and is scanning to a share on a machine on the same subnet using smb.

There are no file repositories set up under CIS Properties->Services->Workflow Scanning->File Repository Setup but the scanning works fine (except that the share host keeps shutting down).

Everywhere I look up scanning in the documentation / on the web it seems to always start off talking about setting up Workflow Scanning  File Repositories.

What I'm wondering is, what essentially is the difference between these and the way it's been done previously by just setting up a Scan template using smb with server, share, and authentication credentials please?

Many thanks
