Not use Windows.ApplicationModel.Package.Current.You can use


ApplicationData.Current have LocalFolder and LocalCache and the tempUse file or folder can put in LoacalCache and the AppData can write in LocalFolder.

If you need use the Users file or folder,you can use the FolderPicker or FilePicker to pick the folder and file.

The StorageApplicationPermissions.FutureAccessList can remember the users folder and file ,but it should use token.
