To be able to share information with other that are stuck with MS product I must export some docs to those formats.

I have a document of 1M odf format, when I save it to Office 2000 format it grows to 20Mb...

I am running 11.2, KDE 4.3.1, repositories are as follow, and I have switched all system packages to the comunity repository of OOo (v3.1.1)

Code:
