I have downloaded the BW10 installer and then the 20GB installation files.
I ran the program and it runs fine (Win 10).

My problem is trying to back up the 20GB of installation files onto a new 32GB flash drive.
When I attempt this it gets as far as the CAB files and then it says there is insufficient available memory for the compressed CAB files.

Are the cab files essential for an installation backup? Which files are essential? How much memory is needed for an installation back up?
