    • compressDirectory

      public long compressDirectory(File directory, OutputStream out) throws IOException

    • decompressDirectory

      public FileUtils.FileCopyResult decompressDirectory(InputStream in, File outDir) throws IOException
      Decompresses a directory from the input stream. Default implementation throws UnsupportedOperationException. Override this method for formats that support directory decompression.
      Parameters:
      in - The input stream containing compressed data
      outDir - The output directory to extract files to
      Returns:
      A FileCopyResult containing information about extracted files
