What is a CMP file?
The .CMP file extension is used by many different software programs for completely different purposes. A .CMP file can be a Windows Connection Manager Profile created by Microsoft, a compressed game archive for the EA Sports FIFA series, a LEADTOOLS compressed image file often used for dental X-rays, or even a JSON character pose file for the Final Fantasy XIV game. Because the .CMP extension is very generic, you must inspect the internal structure of the file to understand exactly what data it holds.
How to open CMP files?
If your .CMP file is a Windows Connection Manager Profile, the Microsoft Windows operating system will process it natively. If the file is a Microsoft SharePoint Content Migration Package, you manage it via server administration tools. For gaming files, you need specific modding utilities like Concept Matrix for character poses. Because a .CMP file has multiple possible meanings, we recommend using viewer.online/cmp to identify the actual format of your file. viewer.online/cmp analyzes .CMP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Never double-click an unknown .CMP file if you do not know its origin. Many .CMP files are standard .ZIP or .JSON files in disguise. You can use a text editor like Notepad++ or a hex editor to look at the first few bytes of the file. If you need to use the data in another program, we recommend file conversion on convert.guru. For example, you can convert LEADTOOLS image files to standard .JPG or .PNG formats, and JSON-based pose files to readable .TXT or .JSON files.
Summary
viewer.online/cmp directly opens and previews .CMP files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
