I'd like a program to compare two directories (network to usb HDD directory), skip any unchanged files; copy over changed files, but archieve/save the older versions (or amend the updated filename).

I don't think SyncToy can do this, what other (free) options do I have?

If you have Window 7 Business, Professional or Ultimate, the versioning aspect is built in to the OS (VSS- Volume Shadow Service). Just turn it on for the usb HDD directory.

Then you can use synctoy or whatever other sync app/service to sync the files between both places.

If your using Win7 home, for $19.95 you can get TimeTraveler which is a 3rd party interface into the VSS service.

ah, didn't think about that.

I assume VSS == Previous Versions for the end user. So just let that act as the archive... what about files that haven't changed; it just overwrites them but doesn't keep multiple versions of the same document archived?

if a file hasn't changed, there's nothing to overwrite, dawg.

Yes, VSS == Previous Versions. You can set it to auto-archive on every file save.
