Re: Unable to locate Save files
Mass Effect uses the folder that is set as the standard Documents folder in Windows.
Here is a link to a guide to change the standard Documents folder in win 7 and here in Win 10.
Make sure Origin and the Game are not running while you change the location. Also, you need to move the "Bioware" or "Mass Effect 2" folder to that new location. Either by applying the move request from the dialogue or manually.
