Problem is Ovi Files is being discontinued on 15th October 2010, so it's not going to work with any Nokia device.
If you want to access your PC remotely from then on, the best place to start researching it would be at
http://maemo.org/. There's a few apps available from there that will allow remote access. Haven't tried any of them yet, but I'm sure they work as the guys over there use them.
