4 reasons I use virtual hard disks in Windows, and you should too
See the advantages of using virtual hard disks in Windows.

Did you know you can make virtual disks on Windows? It’s a cool and underused feature that has been available in the OS since Windows 8. Perhaps you have seen files on your system with the VHD or VHDX extension with a hard drive icon on a PC you’re using. Those are virtual drives, which users create for various needs, and you can also make them. I often use them to share files from my host PC to a virtual machine (VM) using Hyper-V or VirtualBox. Virtual disks also offer portability so that you can move them between systems. In addition to virtual environments, they are helpful for developers, home lab enthusiasts, and IT administrators.
