If you can't find explorer just go to settings-apps and search file explorer.There will be the option.And thank you very much Learn Windows 10 and Computers.Your video has greatly benefitted me,thanks.
Thank you so much for that very informative video about hidden files and file extensions. I am subscribing to your videos from now on. Perhaps you can help me with another issue: I have an external disk drive and although the volume of files is appearing, I cannot open any of those files. Are they hidden somewhere?
