Erased Download folder by changing it to D: disk

I bought a new computer and was trying to change the folders "Documents", "Downloads", "Pictures", etc. to the D:\ Disk.
To change the "Documents" folder, I dd it by creating a folder called Documents in the D:\ Disk and then accesing properties > location > move on the folder which was in the C drive, and then selecting the newly created one in the D drive.
But when I did so with the "Download" folder, I didn't create another folder and I just moved it to D:\
This created the following problem

The download folder was replaced by the D:\ Disk.
How do I create a new one and that it appears on the "Folders" section of "This PC"?
Thank you

It is now in the root of D. Move it back to 'Default' and then try again defining a folder in the first place.

Rename D:\ to Downloads and you should be back to where you were.
