solution-win 7 not showing picture inside SD memory card

I'd a problem extracting images from my SD memo card.I searched whole internet but remained unsatisfied.So just played to that folder from where the contents were not showing.I tried all things like processing like "attrib -a -s -r -h" from CMD prompt, folder's VIEW options,tried to open through Adobe Bridge CS5,etc... atlast, IDK from where I opined to RAR that useless folder of SD memo card...after archiving then I extracted to some safer place(folder) without any folder options....taaaadaaaaa..I got all my 203 pictures back...ENJOY !..WINZIP RAR is very helpful tool yes !
