        throws FileSystemException {
    StringBuffer name = new StringBuffer();

    String scheme = UriParser.extractScheme(filename, name);
    UriParser.canonicalizePath(name, 0, name.length(), this);

    UriParser.fixSeparators(name);//  w ww .j a  v a  2 s . c  om

    // Normalise the path
    FileType fileType = UriParser.normalisePath(name);

    // Extract the root prefix
    final String bucketName = UriParser.extractFirstElement(name);

    return new S3FileName(scheme, bucketName, name.toString(), fileType);
