Cloud Downloads-- Review instructions

[Artbot]

When I download from the Cloud, (on Mac), I just want to make sure I am doing this correctly. Say, I download a material from the Cloud... I then go to my browser's download folder and move the new downloaded file into the designated folders within the Keyshot6/Downloads folder?
I recently downloaded: bdesign_matBall_feltHatChocolate.ksp. Unlike my other Cloud materials that end in ".mtl" is this ".ksp" correct?

Also, then, within Keyshot--the correct and easiest way to find a material is to simple click on the search folder and find it that way?

Thank you
