About .cfml Files
CFML files are ColdFusion Markup Language files that contain server-side source code. They mix HTML with specialized tags to generate dynamic web content.
- Purpose: Build interactive, data-driven web applications.
- MIME Type: Uses text/x-coldfusion to indicate plain text source code.
- Processing: Executed on ColdFusion servers like Adobe ColdFusion or open-source engines like Lucee.
- Software: Can be edited with text editors, Adobe ColdFusion Builder, or web development tools like Dreamweaver.
Based on information from FilExt.com, these files are essential for running ColdFusion applications on web servers.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a CFML file?
A CFML file contains source code written in ColdFusion Markup Language, used to create dynamic webpages. It looks similar to HTML but includes special tags (like <cfset> or <cfquery>) that interact with databases and server logic. These files are processed on the server side before being sent to the user's browser.
How do I open and edit a CFML file?
Since CFML files are plain text, you can edit them with any code editor. Popular choices include Visual Studio Code (with a ColdFusion extension), Sublime Text, Adobe ColdFusion Builder, or Adobe Dreamweaver. Do not use word processors like Word, as they add formatting that breaks the code.
Why does my browser show code instead of a webpage when I open a CFML file?
Browsers like Chrome or Firefox cannot execute ColdFusion code directly; they only display the resulting HTML. If you open a local .cfml file, the browser treats it as text. To view the webpage correctly, the file must be hosted on a web server running a ColdFusion engine (like Lucee or Adobe ColdFusion).
What is the difference between .CFM and .CFML extensions?
There is no functional difference; both extensions indicate a ColdFusion Markup Language file. While .cfm is significantly more common historically, .cfml is also recognized by ColdFusion servers. You can usually rename a file from one extension to the other without issues.
How do I convert a CFML file to HTML?
You cannot strictly 'convert' the source file because it contains logic that must be executed. However, you can save the output of the file. Open the page through a running web server in your browser, right-click, and select Save Page As... to save the generated content as a standard .html file.
What is the MIME type for CFML files?
The standard media type for ColdFusion files is text/x-coldfusion. This identifier helps the operating system and web servers recognize that the file contains text-based programming code. You can learn more about this configuration at text/x-coldfusion.
Is a CFML file dangerous?
As a text file on your computer, a .cfml file is harmless. However, if uploaded to a web server, it executes code that can modify databases or files. Ensure you only run CFML scripts from trusted sources to prevent security vulnerabilities like SQL injection.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
