Ah, then you might be able to save them. Do you remember what folder you saved them in?
Fire up File Explorer and click on This PC and go on your C:\ drive. You should have a folder called Windows.old. Go to that folder and then Users and then user name you had before reinstalling. There should be all your old files prior to reinstalling.
I've done this plenty enough times with reinstallation that while I do backup my files, I don't normally worry about it while reinstalling Windows. Hopefully that'll help you out. If not, I'll sort you out.
