I did something that caused my greyed in read to not let me remove the check. I need to move the folder, because the drive is running out of space and , of course, I can't.
You need to use Command Prompt which you find from Start then Run and by typing cmd into the open box. At the prompt, type attrib /? then decide which of the switches applies to the command you want to execute - possibly -h and possibly -d for an entire folder.
