Support I wiped my phone and my sd card, so why do application folders still exist??

http://androidforums.com – I booted into recovery, did a factory reset/wipe, i did it 3 times, and also wiped the cache partition 3 times and I formatted my sd card in my computer 3 times. And then I put the sim and sd card back in the phone and booted up, set my settings for my phone but never turned on data and never set up a google account yet. So why..in the world.. is there still folders on my phone from the applications which I had installed before I did the wipe? I can't understand it. It has to be on the phone USB storage right? Because I'm sure it wouldn't survive on the sd card if I formatted in my compute (General)
