Steam - Saving game progress?

Hi, is it possible to save game progress on a USB drive with a Steam purchased game.

Ex. I want to save the progress of a Total War Campaign on a USB drive to protect it.
Update: If so, how please.
Update 2: If anyone has tried this, please answer. Thanks Hongming Zhang, It is a single-player, I'm trying to save my campaign (SP) progress, not my multiplayer. I understand what you're saying, I'll try that and save all the Total War files I can find on my computer onto a USB and hope for the best. ;) If anyone has... show more If anyone has tried this, please answer.
