Change Permalink Structure for Downloads

Hi guys! How can I change permalink structure of my download pages. For instanc, I’d like to change it from “my-url.com/downloads/ebook” to “my-url.com/publications/ebook” ?

Thanks Sagar, but my question is about the download area slug, not the single page slug. For instance, I installed WP Download Manager on b-think.com websit and created the download page below:

https://b-think.com/download/e-book-lorem-psum/

But I’d like to rename this url as:

https://b-think.com/publications/e-book-lorem-psum/

How can I change this post type from “download” to “publications”?

Thanks Sagar! Is it available in the free version?
