Question

I would like to cleanup all files from the storageFolder.RoamingFolder in winrt
I can delete individual files but . does not work any ideas on how to aproach this ?

Answer 1

If deleting the contents of a folder is what you want to achieve a recursive method like this would work:

public static async Task DeleteFolderContentsAsync(StorageFolder folder,
   StorageDeleteOption option)
{
   // Try to delete all files
   var files = await folder.GetFilesAsync();
   foreach (var file in files)
   {
      await file.DeleteAsync(option);
   }

   // Iterate through all subfolders
   var subFolders = await folder.GetFoldersAsync();
   foreach (var subFolder in subFolders)
   {
      // Delete the contents
      await DeleteFolderContentsAsync(subFolder, option);

      // Delete the subfolder
      await subFolder.DeleteAsync(option);
   }
}
