speed up import of Acta files
 

I have 100 or so Acta files, which I'd like to import into OO3, and save as OO files, because OO4 will not do that. Doing this one file at a time would take a long time. One idea I have is to keep OO3 around just for that use, but there may come a time where OO3 will not work after an OS upgrade, or for some other reason.

Does anyone out there have a way to automate or speed up the process of importing Acta files and saving them as OO?

Thanks in advance!
