c# - Cant get the files from folder -


i want files , folders sd wp8 pnone. use code:

        private async void getfilesacync()     {         externalstoragedevice _sdcard = (await externalstorage.getexternalstoragedevicesasync()).firstordefault();          if (_sdcard != null)         {             externalstoragefolder routesfolder =  _sdcard.rootfolder;              ienumerable<externalstoragefolder> folders = await routesfolder.getfoldersasync();              ienumerable<externalstoragefile> files = await routesfolder.getfilesasync();              foreach (var file in files)             {                 names.add(file.name);             }              foreach (var folder in folders)             {                 names.add(folder.name);             }              messagebox.show(names.count.tostring());             mainlls.itemssource = names;         }     }

the problem can see folders, there no files (they exist on sd, don't in ienumerable<externalstoragefile> files). so, when launch code - can see folders, no files. tried remove code folders, , leave code have files, there no result. there way solve issue? i'm doing wrong?

you can access files of specific types - is, file type(s) application associated with
