Importing expression maps

I want to use the VSL Solo Strings expression maps created by Mark Petersen. They download as a .rar file, which Dorico doesn’t see in it’s ‘Import Library…’ dialog. How do I get those expression maps into Dorico?

Thanks for your time.

.rar is a compressed format and you need to first unpack the files like with .zip files. .rar is not automatically supported by windows 10 (at any rate not my version) but there are various free downloads that will do the job.

Thank you for patiently answering my very dumb question. I could’ve googled .rar. Sorry, and thank you again.

not a dumb question if you haven’t come across .rar before! I’ve certainly asked dumber.
