Orchid Seeds Storage & Longevity

[Happypaphy7]

Do the seeds from different genera of orchids keep better/longer when kept under refrigeration?
Let's start with Paphs since this is Slipper Forum.

Also, more specific question is that I accidentally found a paper envelop full of dry seeds of Neofinetia falcata from at least 4-5 years ago.
Kept in dry room. What do you think? toss or try sowing anyway?

The short answer is yes, but in a container with dessicant or they will mold.
