Copying free software ... I'm not sure how long this has been in the 
Open Document formats, but it's quite a while. Mind you, I didn't know 
that MS's documents were zip archives - I knew it was true of 
Libreoffice et al.

Libreoffice and its predecessors like to trumpet that they are great 
tools for recovering corrupt MS documents - bit embarrasing for them 
that I have had to - on one occasion - use Excel to recover a corrupt 
OOo spreadsheet! I split open the zip document, retrieved the xml, and 
tried to read it back into calc. Could I heck! It refused to recognise 
it and even when I tried to force calc to open it it passed it over to 
writer. Finally I had to open it in Excel, save it as an xls, and import 
it back into calc.

Cheers,
Wol
