How to see magazine covers of pdf files

[malamute63]

Hello there everyone. I currently use ES File Explorer. When i open the folder with all my pdf magazines, i only see the pdf icon. Is there a way to see the cover of all the magazines at the same time, when looking at the contents of this folder? It works fine on the pc.

Thank you.

I saw a mention in another forum of NextApp's File Explorer app possibly being able to do that, but I'm not sure.
