Is it possible to share this file ?

Yes I can share this, but maybe you can't use this unless you have artificial ears, because of impedance mismatch.
You have to compensate acoustical impedance mismatch between a 2-cc coupler and an occluded ear simulator, first.
You can reference

Plus,

Article about acoustical impedance mismatch {RECD (Real Ear to Coupler Difference)} compensation. You should use Translator to read this.

Can you check measurements for W4 and VSD5 and see if DF compensation is correct? I would like to try with your file too.

Actually, there is many varieties of DF file,
because Diffuse Field is not a specific target, it is just a way to get a Target.
Can you explain more about your measurement condition?
