Thanks Riza. So I was sort of on that track before but it wasn't working. Each of the 4 highlighted backup folders have an alice in wonderland.avi file.
My mistake when I copied them to another folder was that I would rename them alice in wonderland 1.avi, alice in wonderland 2.avi, alice in wonderland 3.avi and alice in wonderland 4.avi. Then when I right mouse clicked and did extract all it would only extract the individual file I clicked on.
What worked is when I save the files to another folder then renamed them alice in wonderland.avi.001, alice in wonderland.avi.002, alice in wonderland.avi.003 and alice in wonderland.avi.004. Then right mouse click extract all on alice in wonderland.avi.001 and the whole file is created.
It a tedious way of recovering large, segmented files from windows backup but it works.
