Open Office saved me today. The story was this. A co-author and I had paper that needed to be completed by tomorrow. It is highly technical and equation intensive. My co-author decided to write his part up in Word Perfect (don’t ask me why, I don’t know!). Mine was in Word. To make them compatible we decided to migrate his part into Word. But whatever he did to help that along corrupted the latest file and so it was unreadable in both programs!
Well, it turned out that it was readable in Open Office which allowed me to save in Word and save the day. It’s free and, as far as I am concerned, should be a necessary install for all PCs.
