speech saved as data instead of aup

I am a new user and saved a spoken recording as data instead of aup. So now I can only listen to this one second fragment at the time, instead of listening to the whole speech. Can I somehow change this from data to aup. I have windows 2003 and my program is audacity 1.2.4.
Thank you Marga
