I used Smart Switch to transfer data from my old phone to my S21 Ultra. It created a folder as a sub-folder of Internal Storage called sdcardbackup in which it put some or all (I'm not clear which at the moment) of the contents of the old phone's SD card. However, this folder is not listed when I look at the contents of Internal Storage in My Files. I can only see it when I run an analysis of storage used and find that it contains around 10GB of video. How can I make this folder fully visible in My Files so that I can sort through its contents and place them in more appropriate places?
