File Extension BKF

.BKF File

File extension: BKF
File type: Backup Utility Backup Set


Notes about the BKF file extension:



To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The BKF file type is primarily associated with 'WindowsXP' by Microsoft Corporation. Note: This is default; can be renamed to any extension. For XP Home this utility is not installed by default. You have to install it from the added value directory of your XP Home distribution disc. Once installed it shows up in the Start | Programs | Accessories menu. If you make multiple backups a catalog of those backups is kept on the hard disk in the folder \Documents and Settings\All Users\Application Data\Microsoft\Windows NT\NTBackup\catalogs51. If you have a backup file you are trying to recover files from and that file is not listed in the catalog then the Windows Backup program will not restore from that file unless you delete the catalog. Then, because it has no other data to work from, Windows Backup will recover files from the backup.
