How to handle 404 error for files in MVC5?

Question

I wrote Controller to handle 404-page error for my MVC5 application as it was showed here . However it works only with HTML-pages that has controller and method.

It doesn't work with files\\images that just has a link inside the site. For example Sample.chtml:

    <a href="@material.FilePath"><i class="material-icons left">file_download</i>@material.Title</a>`

where FilePath is just reference to ~Content/images/... or ~/Content/Files/file.pdf.

When I try to go through this links I get standard 404 NotFound page and Error controller or Application_Error from Global.asax.cs doesn't call.

Especially I need this handler for file-not-found case. How can I solve this problem?

Edited : Important moment : this files has just pure-html-link and no controller\\method defined.

Search NuGet for the MvcNotFound package. It handles all of this very neatly for you.
