I am trying to include a True Image file I made (5 GB) in the BartPE DVD so I can boot and restore from the DVD.

I included the image file in the Include directory, when creating the DVD, Bart sees it and injects into the image - as 1 GB file

I have also tried to insert the image using UltraISO, but the 5 GB file is inserted as 1 GB file as well. I am baffled on why the image is chopped this way. Any ideas?

There is a wrap around at 4 GB.

A 5 GB file at boot DVD is difficult, currently almost impossible.

Dosn't True Image split image file?
