There are software tools available to do this, what is your ultimate goal? would it be to take the ext. hard drive with you to play on other pc's? is it a space problem? Be aware that ext. drives typically do not operate as fast as internal, so expect some frame rates to decay. System mechanic 7 is a multi-utility tool to do many things, but it can move existing software, you can use the demo for free to move what you need to. I don't have anything to do with Iolo, but I appreciate a good software.

The easiest is to simply copy your save games to your desktop(note the location of the saves in that game folder), un install the game in it's existing location and re install on the new drive. Then copy your save games to the correct folder that you took note of. This requires no extra software, keeps your game at the level you're at and does a clean uninstall of the old location. Edit: This isn't a thumb drive, like a 1 gig or something, is it? It's a proper external drive? If it's a proper external, then read on. If it's a small thumb drive with a capacity less than 5 gig (as big as I've seen them), you're on shaky ground. The minimum recommended space is 4 gig for that game. The reason you will have to reinstall, is that for the game to work in it's new location, registry values need to be written. You can go ahead and purchase drive imaging software, but most don't give you an option to just image select folders. It'll want to image the entire old drive. If you DO buy one that will image only files you select, again, you'll have to dig into the directory tree to select those files. For what you want to do, it just doesn't make economic sense to purchase that software suite. If the external is large enough for the game, the route I described is still easiest and cheapest. Typically, save games for most Pc games are located in a folder called "saves" or "savegame" for example. It's pretty intuitive as to what the folder is called. That's the puppy you need to copy over to the new game location, once it's installed. It also has to go in the same place, within the game folder. For example, if it's located currently in C:whatevermaybeprogramfilesthegamesavegame....then it has to go into YOUR External drive letter here:whateveryouwanthere(maybegames)thegamesavegame What's important is where it goes within that game's folder. The game, when you start it, will be looking to see if you've played it before and if you've saved your progress. If your saved games aren't in the right place, it'll start you at square one. This approach isn't really difficult at all. It just requires that you pay attention to getting the save games out, before you uninstall from your old location and put that saved game folder back in the right spot in the new location. One other thing. Some games won't create a new save game folder until you play it once, so if in the new location you don't see a saved game folder, that'll be why. Just play it once, it'll create it, then it's a simple matter of replacing the folder the game just created, with the one you backed up from the old install. If you don't uninstall the game from the old location before installing in the new, you'll be wasting whatever space you could have freed up on the old internal drive (if you needed it in the first place), the registry might get a little screwed up as far as playing that game is concerned, shortcuts on the desktop for the game can get buggered up and point to the wrong location and a host of other things including the possibility that the game will crash. It's really not difficult.
