using non Reason files in Reason

[NRGboy]

Can someone please tell me how I can view non Reason files in Reason and use them?

I've got a copy of Essential Hardstyle Tools Vol 2 but when I try and open them in Reason they aren't there.

How can I change the format so that I can use them?

you can use wav files in the redrum or the nn9 sampler .
