Be careful.
It is important to understand that the .bak file extension is not limited to a particular set of applications. Other programs besides the intended ones can also use the .bak extension to create files. This includes potentially harmful programs or malware that may generate .bak files for various purposes. Be especially cautious with .bak files coming from untrusted or unknown sources.
Can't open a .bak file?
When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize an extension, you receive the following message:
Select an app to open this .bak file
To set the .bak file association in Windows 11, you can follow these steps
- Open the Settings app by clicking on the Start menu and selecting the gear icon.
- In the Settings app, click on System and then select Apps from the left-hand side menu.
- Scroll down and click on the Default apps option.
- Under the Default apps section, you will find various categories such as Email, Web browser, and Music player.
- Locate the category that matches the file type you want to associate, such as Photos for image files or Video player for video files.
- Click on the current default app listed under the category. A list of available apps will appear.
- Choose the app you want to set as the default for that file type. If the desired app is not listed, click on More apps to see additional options or click on Look for an app in the Microsoft Store to search for apps in the Store.
- 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 .bak file association. Many applications can open .bak files without requiring any specific file association to be set.
