Just locate the folder you want to replace.In order to replace a folder, follow these steps. That already had a folder of the same name actually. Windows used to replace the folder whenever it was copied to a destination. In either case, the first folder’s contents will be merged along with the second as well. If you guys see a prompt telling you the destination folder has files along with the same name you can also replace them, or skip over them.The destination folder will also have files from both.
If they do not have the same name, then just rename them so that the names are identical. Windows 10 can automatically merge the contents of two folders that actually have the same name when you guys copy the folder from one location to another.
