  2. Check if the Folder Exists
  3. try
  4. {

  7. }
  8. catch(FileNotFoundException ex)
  9. {
  11. }
Read all Folders

  2. foreach (var folder in folders)
  3. {
  4. MessageBox.Show(folder.Name);
  5. }
Rename Folder
  1. var folder = await ApplicationData.Current.LocalFolder.GetFolderAsync("FolderName");
  2. await folder.RenameAsync("RenamedFolder");
Delete Folder
  1. var folder = await ApplicationData.Current.LocalFolder.GetFolderAsync("FolderName");
  2. await folder.DeleteAsync(StorageDeleteOption.PermanentDelete);
Create File
  1. var file = await ApplicationData.Current.LocalFolder.CreateFileAsync("FileName.txt", CreationCollisionOption.ReplaceExisting);
Write File
  1. var file = await ApplicationData.Current.LocalFolder.CreateFileAsync("FileName.txt", CreationCollisionOption.ReplaceExisting);
  2. var stream = await file.OpenAsync(FileAccessMode.ReadWrite);
  3. using (var writer = new DataWriter(stream.GetOutputStreamAt(0)))
  4. {
  5. writer.WriteString("Welcome to windows phone");
  6. await writer.StoreAsync();
  7. await writer.FlushAsync();
  8. }
Read File
  1. var file = await ApplicationData.Current.LocalFolder.GetFileAsync("FileName.txt");
  2. var stream = await file.OpenAsync(FileAccessMode.Read);
  4. using (var reader = new DataReader(stream.GetInputStreamAt(0)))
  5. {
  6. var bytes = await reader.LoadAsync((uint)stream.Size);
  7. var s = reader.ReadString(bytes);
  8. MessageBox.Show(s);
  9. }
Check if a file exists
  1. try
  2. {
  3. file = await ApplicationData.Current.LocalFolder.GetFileAsync("FileName.txt");
  4. MessageBox.Show(file.Name);
  5. }
  6. catch (FileNotFoundException ex)
  7. {
  8. MessageBox.Show("file not found");
  9. }
Read all File
  1. var files = await ApplicationData.Current.LocalFolder.GetFilesAsync();

  4. {
  5. MessageBox.Show(file.Name);
  6. }
Rename File
  1. var file = await ApplicationData.Current.LocalFolder.GetFileAsync("FileName.txt");
  2. await file.RenameAsync("FileRename.txt");
Delete File
  1. var file = await ApplicationData.Current.LocalFolder.GetFileAsync("FileName.txt");
  2. await file.DeleteAsync(StorageDeleteOption.PermanentDelete);
Copy File
  1. var file = await ApplicationData.Current.LocalFolder.GetFileAsync("FileName.txt");
  2. var folder = await ApplicationData.Current.LocalFolder.GetFolderAsync("FolderName ");
  3. await file.CopyAsync(folder);
Move File
  1. var file = await ApplicationData.Current.LocalFolder.GetFileAsync("FileName.txt");
  2. var folder = await ApplicationData.Current.LocalFolder.GetFolderAsync("FolderName ");
  3. await file.MoveAsync(folder);
