How to backup games in Windows
There are number of different methods games can be backed up on your computer. Depending on the game, when it was made, and who made it often determines how games are saved. Below is a listing of different locations you'll find saved games. Once the saved data is located, copy the folders containing the saved game data to an alternate source such as a different hard drive or a burnable CD (Compact Disc). To recover the saved data, you can copy that folder back to its original location.
Documents and Settings, My Documents, or Application Data
Most recent Windows games are storing all saved games and game settings in your My Documents folder or other section of your documents under a folder named the same as your game.
Start by checking the My Documents folder. Additional information about how to get into My Documents is available on our My Documents definition page. In the My Documents folder, look for a folder with the name of the game or developer of the game. If not found, open the My Games folder in My Documents and see if your game is listed there.
If you're unable to locate the game in My Documents, open the Application Data path below, where <user> is your Windows username.
C:\Documents and Settings\<user>\Application Data
Game directory
If you're still unable to locate the saved games, the next best location to find them would be in the actual game directory. Many Windows games are stored in the Program Files directory under the name of the game or its developer. For example, Maxis games are in the Maxis directory (C:\Program Files\Maxis\<game name>).
Other location
Apart from the two common locations above, a game could be saved anywhere on the hard drive. If you cannot find the game under Program Files, right-click the game shortcut and select the Properties option. In the Properties window, under the Shortcut tab, the shortcut is shown and clicking the Find Target button opens the folder of the game.
Online games
If your game is an online game, it's likely your game settings and characters are saved online and cannot be saved to a backup.
