posted by awaiz is risky,you will delete some improtant files by doing it. Try using file explorer to deleted anything you want,use Fexplorer. Or didnt you tried removing theme using Application manager?
Animated theme you downloaded must be created on ownskin.com,so you should try finding that theme in ownskin.com,& download it again.The animator would be attached in the theme when you install it...Good Luck,Anyway animated skin slows down your N70,thats why ,im not using animated theme.
I prefer you to convert those youtube videos(which is flv formated)then convert it into MP4 format or 3G format.Which N70 supports. N70 doesnt support FLV,unless you have an application to play that FLV video.
