Hi,
Thanks for contacting us here about this extension.
I'm looking for a feature where front-end users can select multiple files to download as zip.
From what I see in your demo, the multiple selection is possible only inside the same folder/category.
Is there a way to allow users to select files across categories and then download a zip file at the end of the navigation and selection?
This feature is not possible currently. It's useful in some cases as yours.
But it's like a maze with a bunch of files and folders on frontend.
Also, Is it possible to display a custom thumbnail image for each single file?
Yes, you can add you custom icon. For more information:

This could be possible but you should customize code, if you do not know how to do, our dev will help you.
P.S: I removed your duplicate ticket on this forum.
Hope it helps!
Cheers,
