In the further part of this page we have added a list of programs that should open your CFM file. It is enough you choose a proper application for your operating system, download and install it.


Files ending in CFM are source code files in the ColdFusion Markup Language. ColdFusion ML is a scripting language developed by Allaire (now part of Adobe) for server-side Internet applications. Typically, CFM files are web pages with Coldfusion script code running on a Coldfusion server. The html code is added to the file by the server so that it can be displayed to the user in a web browser.

Coldfusion offers the developer a variety of functions and tags such as database queries, image manipulation and mathematical operation as well as formatting options. Coldfusion Server is few because of Adobe's proprietary license. With Railo there is also an open source server, which does not support all features and tags of Coldfusion.

CFM files are just text files that can be processed by a ColdFusion server. They can be opened and edited in any text editor, however it is recommended to use editors with developer functions such as syntax highlighting for easier work.

How to open a CFM file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the CFM file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a CFM file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support CFM files. At this point we are looking for disk space where the application was installed in and we can link it with a CFM file. Since then, our operating system will use the selected program to support all CFM files.

Other issues

Despite the described problem with CFM there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the CFM file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the CFM file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
