Wmf file can Rhino work with it?

Hi,
V5
I have tried to open a .wmf file or import such as a basis to start afresh over it creating some numbers I need, however I cant see the file either as open or import. It is vector, so how can I do this ?
I have exported it as eps postscript level3 (default setting) in Affinity Designer but Thino says cant open old AI file !
