Windows can't open your ARP file?

When you try to open a file by double-clicking it, Windows looks at the file's name to figure out what to do. If Windows doesn't know the file type, it'll ask you to choose an app to open this ARP file.

To set the ARP file association in Windows 11, you can follow these steps

  1. Open the Settings app by clicking on the Start menu and selecting the gear icon.
  2. In the Settings app, click on System and then select Apps from the left-hand side menu.
  3. Scroll down and click on the Default apps option.
  4. In the Default apps section, you will find various categories. They include Email, Web browser, and Music player.
  5. Locate the category that matches the file type you want to associate. For example, choose Photos for image files, or Video player for video files.
  6. Click on the current default app listed under the category. A list of available apps will appear.
  7. Choose the app you want to set as the default for that file type. If the app you want is not listed, click on More apps to see more options. Or, click on Look for an app in the Microsoft Store to search for apps.
  8. After selecting the app, it will become the default choice for opening files of that type.

It's worth mentioning that you don't always need to set ARP file association. Many apps can open files. They don't need a specific file association to be set.

Handle ARP files with care

Exercise caution when handling ARP files from unknown sources. Files from certain sources can threaten your computer's security. They might contain malware, viruses, or harmful software. To minimize risks, avoid downloading or opening unfamiliar ARP files. Use trusted antivirus software to scan files from unknown sources before opening.
