Hey all,
I know that a lot of software allows you to open older files created in a lower version of the same software into a higher version such as CorelDRAW X3 will open any Corel file that is lower than X3 but not higher.
Is his true for Real Flight as well ? I have G4 and have upgraded it to G4.50 so can I import planes from G3 or G3.5 and have them display correctly. Didn't want to assume I could and fowl things up.
