If it tells you that the folder already exists, you want to delete the old folder and replace it with the new one you are currently pasting. You will have to open your launcher and install custom content.ħ.
Once your downloads are done, go into your 'The Sims 3 Old' folder and go to the folder titled 'Saves.' Copy or Cut these files and Paste them into 'Saves' under the new 'The Sims 3' folder.Ĩ. Once your saves are moved, start your game. If not, answer the questions I put at the start of this reply.
