Help!

I have the Sims 4 on steam and just got an internal drive. I transfered all my folders over no problem, but in doing so it deleted everything along with all of my folders. I tried to delete and reinstall the Sims 4 in order to get my folder back, but nothing has worked. I have been trying to fix it for a week now and nothing will.

Can someone please help me fix it? If there is no fix is there anyway for me to get a refund on all my DLC so I could get it on EA and/or transfer it over to EA?
