What happens to my files when uninstalling Ubuntu (installed from wubi)

view story

http://askubuntu.com – (original OS win7) I've installed ubuntu from wubi (so I can easily uninstall it after I try it), I've also installed some apps. I am wondering if I uninstall ubuntu, will all the files I created and apps I installed in ubuntu be removed as well or would I have to manually remove them after? (HowTos)
