The BCK (VMX Backup File) extension is used by VMX files produced by VMWare virtualization software. A BCK file serves as a backup for a VMX file and is used to preserve the VMX file's settings and attributes in the event of corruption or other loss of data. The BCK file is used to rebuild the settings of the original VMX file, restoring it to its original functioning condition.
A BCK file is created when any changes are made to the settings or data stored in a VMX file. This makes it easy to restore a VMX file to its original state if something goes wrong during operation of the virtual machine, such as if a hardware conflict arises or if any operating system updates render the VMX file dysfunctional. The BCK file databases all changes made during the operation of the virtual machine and can thus be used to roll back a VMX file to those same settings, resolving any issues with the VMX file.
Data Format
BCK files are saved with a binary format and contain all necessary data that was stored in the original VMX file. This data includes kinds of configurations including storage, memory, CD-ROMs, network connection information, etc. that are associated with the original virtual machine image.
Similar File Types
BCK files are related to other similar backup files such as .VMSD, .VMSS, and .VMSN. Each of these serves a different purpose when backing up a virtual machine image created by VMWare.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BCK) 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 .BCK 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 .BCK 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 .BCK 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 .BCK extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BCK file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BCK 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 .BCK file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BCK file) will be extended to the maximum.
It is also good to check
- if the .BCK file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
