I downloaded and intalled the Tweak UI on my computer. I was trying to to fix my external drive. So in the process I lost my C drive icon in the my computer section. There was one recovery folder in my E drive and it disappeared too. I think I might have done something wrong and messed it up. I have a windows XP computer. I followed the steps and still failed t restore the icons. Please help out what should I do to get them back.
