VMDK ( .vmdk) is a virtual machine disk file used by VMware virtualization software. It shares the same format as other virtual disk formats such as those used for VirtualBox and Parallels Desktop virtual machines. VMDK files contain hard drive data that has been “zipped” and packaged for use by a hypervisor, like VMware Workstation, which abstracts physical hardware and allows multiple operating systems to run on different hardware profiles simultaneously.
The VMDK format is the most common format type used in VMware products such as Workstation, Server, and vSphere. A VMDK file can be thought of as a storage medium containing everything needed for a virtual machine to run including bootable information, application data, memory blocks, and disk space. This file type helps simplify server resource deployment by allowing system administrators either to create or export-import complete virtual environments, complete with network connections, physical hardware links, and operating system configurations.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .VMDK) 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 .VMDK 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 .VMDK 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 .VMDK 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 .VMDK extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .VMDK file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .VMDK 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 .VMDK file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .VMDK file) will be extended to the maximum.
It is also good to check
- if the .VMDK file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
