Robert- A general comment. None of the standard CD burning software Apps of which I am aware will split a large (>650mb)file to copy it across two or more CD disks. Windows does not support this. But Nero 6 Burning "Backitup" (and at least some versions of bundled Nero, single device apps) will span CD's by making file level and/or sector level back backups of smaller files.
Look in UFT Help>About>System for info on library file naming conventions. According to UFT Help, Images can also be extracted from UFT in Build>Multimedia.
