The following code example demonstrates the GetFileNames method. For the complete context of this example, see the IsolatedStorageFile overview.

    String[] dirNames = isoFile.GetDirectoryNames("*");
    String[] fileNames = isoFile.GetFileNames("Archive\\*");

    // Delete all the files currently in the Archive directory.

    if (fileNames.Length > 0)
    {
        for (int i = 0; i < fileNames.Length; ++i)
        {
            // Delete the files.
            isoFile.DeleteFile("Archive\\" + fileNames[i]);
        }
        // Confirm that no files remain.
        fileNames = isoFile.GetFileNames("Archive\\*");
    }


    if (dirNames.Length > 0)
    {
        for (int i = 0; i < dirNames.Length; ++i)
        {
            // Delete the Archive directory.
