Assuming you are talking about Word 2007 (or 2010) then yes.
If you associated the odt extension with Word, double-clicking the file in
Windows Explorer should do the trick. If you haven't, just start up Word,
click the Office button and select "Open". In the dialog, ensure that either
'All files (*.*)' or 'OpenDocument Text (*.odt)' is selected to locate your
odt files.
