Microsoft Backup Format | Microsoft | Backup Files |
The BKF file extension is associated with Microsoft Windows, an .OS operating system. It is a Backup File and used by the Windows NT Backup Utility, a component of the .NT family. This utility can be used to backup files and folders on local drives, as well as remote ones. The BKF file stores the data that is backed up and allows for later restoring of the backed up files and folders.
A full backup of all specific files on a computer is often accomplished by creating a BKF file and then saving it to an external storage media such as a flash drive or a disk. This is necessary for safe keeping of important data in case something happens to the main folders, such as when a computer develops a virus or crashes. As the files within BKF file remain compressed during backup, they will take up less storage space than the actual sum of their original sizes.
Similar Extensions
Similar extensions are .QB, .QBB, .QBM, .CPD, .CTF, and more.
Compression Strength
BKF files are compressed using Lempel–Ziv–Markov chain Algorithm (LZMA). It was specially designed by developers for Windows NT Backup Utility for compressing large amounts of data in a short amount of time at very low sizes ratio.
Opening BKF Files
The most convenient way to open BKF files is to use a dedicated program such as WinRAR. This program helps to successfully extract any stored items, so users can access the needed file, folder or document without any complications.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BKF) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .BKF extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .BKF file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .BKF extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .BKF extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BKF file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BKF file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .BKF file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BKF file) will be extended to the maximum.
It is also good to check
- if the .BKF file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
