Is there a way to serve unknown file types in IIS 7?

I only want to do this for a single directory where execution is turned off and everything will be served as a static file.

As it is now, I have to add each file extension that I want to serve as a MIME type. I want to serve everything. How can this be done?


You can add an universal MIME type by using the extension "*" and the type "application/octet-stream": http://support.microsoft.com/kb/326965

    Click MIME Types. Click New. In the Extension box, type an asterisk (*). In the MIME Type box, type application/octet-stream – emirjonb Oct 30 '15 at 8:36

Instead of going through the MMC like the kb article suggests, you can also just create a Web.config file in the directory, with the following content:

<?xml version="1.0" encoding="UTF-8"?>
            <mimeMap fileExtension=".*" mimeType="application/octet-stream" />

Just in case pictures help. This is for IIS v10 installed on a windows 10 box:

  1. Go to MIME Types feature of the virtual directory of your website:
