How to Open a CFM File

By Jeff Grundy

ColdFusion Markup (CFM) files are markup files created by the ColdFusion Web scripting application from Adobe. Unless you're a Web developer, chances are that you probably don't have an application designed to handle CFM files specifically. Although Windows doesn't support the opening or viewing of CFM files by default, you can use Notepad -- the built-in Windows text editor -- to open, view and edit the files without the need of the ColdFusion platform application.

Step 1

Click “Start” and then “Computer.” Navigate to the folder containing the CFM file you want to open. Double-click the folder containing the CFM file to display its contents in Windows Explorer.

Step 2

Right-click the filename of the CFM file you want to open. After the pop-up menu appears, click “Open With Notepad." If the Open With Notepad option doesn't appear on the pop-up menu, click “Open With…” and then select “Notepad.”

Step 3

View or edit the CFM file as needed in Notepad. After viewing or editing the contents of the file, click “File” and then click “Save” to save any changes you made. Click “File” and then “Exit” to close Notepad.

Tips & Warnings

  • If you want CFM files to open in Notepad automatically, click “Start,” “Control Panel” and then “Default Programs.” After the Default Programs window appears, select CFM in the list and then click “Change Program.” Click “Notepad” in the Other Programs section and then click “OK.” After associating CMF files with Notepad, you no longer need to right-click the file name to open it.
  • You can also view CFM files in most Web browsers. However, you might not be able to view the page correctly if associated or dependent files are not also in the same folder as the CMF you want to view.
