Listbox to Open Document Spreadsheet (*.ods) with TT's Zip-Package

General

First thing I would try is to :

  • create a small test document,
  • save it as ods,
  • Unpack it
  • recompact it with TTZip.

If it is recognized as valid, then TTZip is just fine, and something is wrong with the format of your XML.
