How to Open the BKF File on Windows 11/10
How to open the BKF file on Windows 11/10? Unfortunately, Microsoft has removed NTBackup.exe from Windows 11/10, so there is no way to recover BKF files on Windows 11/10. However, this can still be achieved by manually downloading and running the NTBackup utility to open the BKF file.
Here are the steps for restoring data with NTBackup.
Step 1: Launch the NTBackup.exe. Choose Restore files and settings and click Next.
Step 2: Double-click the backup identification label to find your BKF file and check the box. Then, click Next. If you can’t find the BKF file, you can click the Browse… button to search for it.
Step 3: Click the Advanced… button. Then, click the drop-down menu to choose a location to restore files. You can choose Original location, Alternate location, or Single folder.
If you choose the Alternate location, you can click the Browse… button to choose the location by yourself.
Step 4: You can choose how you want to restore files that are already on your computer. There are 3 options – Leave existing files (Recommended), Replace existing files if they are older than the backup files, and Replace existing files.
