How can be changed the path to save folder in FIFA10 (PC)?

You can use a symbolic link if you don't want to move all of your documents:

• Move the save folder to where you want it to be.

• Open a terminal window with admin privileges.

• Use the following command:

  mklink /D "C:\Users\ACCOUNT\Documents\Path\To\Saves" "D:\Path\to\new\folder"

Once this is done the game should save its files to the new location without even knowing about its existence. Just make sure the target is valid (e.g. in case it would be a removable drive).

To revert the whole thing just remove the symbolic link (which will look like a shortcut) and move the folder back to its original position.

I don't know wether one is able to change FIFA10s save directory, but as I think this isn't your main problem, I may still help you :D

The folder Documents isn't a real folder. It's just a view on different folders.
Which means, you can easily alter/add a new location. (FIFA will still store its files to "documents", but documents is on your other partition)

Windows 7

1. Create a new folder that you want to assign as My Documents folder, if you have another drive or partition ex: drive D: I recommended that you create My Document Folder to that drive.

2. browse to "C:\Users\" using Windows Explorer (Press WINDOWS KEY + E to access this). Then, right click on My Documents and select Properties: Then Click Location Tab

3. Then click Move then browse to new location for your My Documents folder. Once you find new folder for your document click Select Folder.

4. then click Apply, there will be pop up message to confirm the changed, click Yes to move your documents to the new location, or click No to leave your documents in the original location.
