Re: [PC] Importing a save file from Mass Effect 1
If your question is about importing ME1 characters to ME2 do this:
Navigate to your "Documents\BioWare\Mass Effect 2\Save" folder and create a folder named "ME1" (Without the quotes) inside the "Save" Folder.
After you finished ME1, copy the Mass Effect Saves from the Mass Effect save folder ("Documents\BioWare\Mass Effect\Save") into the "ME1" folder you created.
Now ME2 should "see" your ME1 characters.
