First, check your computer's Downloads folder—it's possible you never deleted the .zip files you later extracted. Check onedrive.com too, both in My Files and the Recycle Bin. Even if you don't use OneDrive now, it could have synced your data at some earlier point.
If you don't clear your browser data regularly, you could also go through your history looking for downloads. This would be tedious, of course, but it's up to you whether it's better than starting from scratch.
