Introduction

MIME (Multipurpose Internet Mail Extensions) types are essential for web servers to correctly identify and serve different file formats to browsers. When browsers encounter unknown file extensions, they may not handle them properly, potentially causing download prompts instead of displaying content or triggering security warnings. DirectAdmin’s MIME Types management allows you to define how your server should handle specific file extensions, ensuring proper content delivery and user experience.

This guide explains how to add custom MIME types using the Advanced Features > Mime Types section in DirectAdmin. Adding appropriate MIME types is particularly important when hosting specialized file formats, custom applications, or emerging web technologies that may not be included in the server’s default configuration.

Prerequisites

Access to DirectAdmin control panel with the necessary permissions.

Step-by-step Guide

Step 1: Access DirectAdmin

Step 2: Access Mime Types

Go to the Advanced Features section and click on Mime Types. You will see the list of MIME types that have been created.

Step 3: Add a New MIME Type

In the Add MimeType section:

MimeType: Enter the MIME type you wish to assign (e.g., application/x-shockwave-flash).
Extension: Enter file extension that will use this MIME type (e.g., swf)

Then, click Add.

You can add different extensions to the same MIME type by repeating the step and entering a different extension.

Note: The MIME types listed are only those that are newly added by users. You can see the complete list of the current MIME types installed by clicking Click here for a list of the current MimeTypes installed on the system at the bottom of the page.

Step 4: Verify the changes

You can verify the addition by referring to the list of MIME types below. To test, upload a file with the new extension to your website and access it via a browser. The browser should now recognise and process the file as per the MIME type.

Conclusion

Adding MIME types through DirectAdmin’s MIME Types interface is a straightforward process that ensures proper file handling and content delivery. By defining appropriate MIME types for your file extensions, you enable browsers to correctly interpret and display your content, improving user experience and preventing compatibility issues.
