Can't open files/folders in C drive
Help! Not very computer literate. If I go to the C drive on my computer and try and open a file there, it asks me what program I want to use to open the file. Only if I work my way through all the options one by one, none of them work for some reason or another. So in the end I've got stuff on my C drive that I don't know what it is and can't open? Help?!!!
