The above answer is very valid and I do it all the time to back-up routes and sessions. However, if you want to save everything you have done, the easy and fool proof way is to open in explorer your TS12 folder, go to users and locate the local folder (Or do this with users folder). Copy it to a flash. Unplug the flash and re-install whatever you have to do: format drive, re-install Windows and re-install TS12. After all that, put the flash back and just copy the user or local folder to anywhere in the TS12 folder. Presto! You should have it in your CM "own content". Users-local folder have all your assets, routes and sessions inside, so moving it, moves everything in one shot.
