Hi again Nick,

This problem appears to be Mac-specific, I have had more luck with a .doc f=
ile created natively in Windows :-)
Now POIFSLister shows the ObjectPool and the item in it:

Root Entry -
  SummaryInformation <(0x05)SummaryInformation> [412 / 0x19c]
  DocumentSummaryInformation <(0x05)DocumentSummaryInformation> [280 / 0x11=
8]
  WordDocument [4142 / 0x102e]
  1Table [2087 / 0x827]
  ObjectPool -
    _1432368106 -
      CompObj <(0x01)CompObj> [76 / 0x4c]
      ObjInfo <(0x03)ObjInfo> [6 / 0x6]
      Ole10Native <(0x01)Ole10Native> [568849 / 0x8ae11]
      EPRINT <(0x03)EPRINT> [5000 / 0x1388]
  CompObj <(0x01)CompObj> [113 / 0x71]
  Data [4096 / 0x1000]

Please can you point me to any resources which could help me to save the em=
bedded file to another file (i.e. read all the bytes and save them somewher=
e)?

Thanks,

- Chris
