You can use Metadata Extraction Tool

The Metadata Extract Tool includes a number of 'adapters' that extract metadata from specific file types. Extractors are currently provided for:

  • Images: BMP, GIF, JPEG and TIFF.
  • Office documents: MS Word (version 2, 6), Word Perfect, Open Office (version 1), MS Works, MS Excel, MS PowerPoint, and PDF.
  • Audio and Video: WAV, MP3 (normal and with ID3Tags), BFW, FLAC.
  • Markup languages: HTML and XML.
  • Internet files: ARC

If a file type is unknown the tool applies a generic adapter, which extracts data that the host system 'knows' about any given file (such as size, file name, and date created).
