Issues viewing CC in CAS create mode

Okay so what I'm looking to do is extract the meshes of items so I can load them all up on blender... but whenever I go through the create CAS options to make a copy and then edit the mesh, nothing from my mods folder shows up. Am I doing something wrong? I'd go through the "my cc" option but I'm relying heavily on the thumbnails to tell which item is which. Do I need to set them up somewhere? Is there any way to view them simply from thumbnails? 
I'd appreciate any advice I can get, I'm new to the program! <3
