Ask the person who is providing you the v7 file to use `SaveAs` and make sure they pick Rhino 6 as the target file format.

Be advised that Rhino 7 features most likely won’t end up in the v6 version (or older if you are picking that).

Apart from what Nathan wrote, if you search this forum, you will find a converter utility that was written by a user.

just type in front off the magnifying glass version converter and press enter.
