So the first thing to do is to make the new local account to see if the user folder is created as expected and visible.
Create a local user or administrator account in Windows - Microsoft Support be sure to create the new account with administrator privileges and not just a Standard account.
When you have signed in to the new account (I suggest signing out the old account and in the new one) be sure it is accessing everything and folders are visible in File Explorer.
Depending what everything is you have downloaded and where you saved it you should be able to copy files to the new account default folders, Documents, Pictures, Downloads etc.
Open File Explorer and expand This PC > C:\ select the Users folder. You should see the new account folder profile name. If you create an account called Face then the folder should be C:\Users\Face. See if the old account folder is visible in the new account. You may not have access to the original user folder but you should have the option to allow you access.
Just to check what is the current version and build of Widows 10, type winver in Search and select the top result.
