I've already seen [this question][1] and [this one][2], but neither explicitly tells me whether a particular game syncs *saved game* files to the Steam Cloud.

**Do all Steam games with Steam Cloud enabled automatically sync your saved games?  
Are there some games that don't?  
How can I tell which are which?**

I ask because I'm about to go on a bloodthirsty purge of my locally-installed Steam games, and I don't want to lose my saves.  The Steam Cloud seems like a perfect option (redownload the game, get all your saves back at the same time), but I don't want to accidentally delete a game and then later discover "Oh, by the way, we didn't sync your saves, but we did sync your graphics preferences! [Ha ha!][3]"
