What is a .VMSD file?
A .VMSD file is a special kind of computer file used by certain programs to remember specific details about a snapshot of a virtual machine (VM). Think of a virtual machine as a computer within your computer that can run a different operating system or settings. The programs that use .VMSD files are called VMware Workstation and VMware Fusion. These programs let you have multiple virtual computers on one physical computer.
When you take a "snapshot" of your virtual machine, it's like taking a photo of what your virtual computer looks like at that moment, including what programs are open and what files are being used. This snapshot gets saved in a file with the extension .VMSN, which is like the photo itself. The .VMSD file is like the photo's description, telling the virtualization software all the important details about the snapshot, but it doesn't contain the snapshot. It works together with the .VMSN file to help the software understand and load the snapshot when needed.
To open a .VMSD file, you need to use VMware Workstation or VMware Fusion. These programs are designed to create and manage virtual machines, allowing you to run different operating systems on your computer without needing to restart it or have another computer.
Here's how you create a .VMSD file: When you decide to take a snapshot of your virtual machine using VMware software (like Fusion for Mac users), the software automatically creates both a .VMSN file (the snapshot) and a .VMSD file (the details about the snapshot). If you're using Fusion, for example, you can take a snapshot by going to the menu, selecting "Virtual Machine," then "Snapshots," and finally "Take Snapshot." The software then saves these files in a specific location on your computer, usually within a folder that has all your virtual machine's files.
In summary, a .VMSD file is a small but important part of using virtual machines with VMware software, helping the software manage snapshots of your virtual computers.
