How to get a parent folder on Windows Store App(Windows Runtime) -

i whether storagefolder , storagefile have parent folder , data if has on windows store app project.

i found "getparentasync" method @ msdn. however, seems works windows 8.1.

please tell me how realize same process on windows 8.0 project.

currently in 8.0 there no way parent of folder. imagine reasoning way move out of folder given access user through folderpicker etc.

in fact in 8.1 getparentasync may fail if don't have permission folder. in apps need access parent folder it's because user has moved down through folder structure , moving up. end maintaining own navigation stack of folders.
