Carbide 6 file dos not open in carbide 8

As noted at:

https://carbide3d.com/blog/create-v8/

Create V6 files do not load into V8

Moreover, for 3D files:

Files from prior versions will not load 3D components in V8. There were too many changes to the internal format for the new capabilities of 3D, and there was no good way to map existing 3D components into V8.
