Virtual Disk

A virtual disk is a storage file that acts like a physical hard drive, but exists as a file within a computer’s existing storage system. It allows multiple virtual disks to be created, used, and managed independently, often for running different operating systems or applications in a virtual environment. Think of it as a "storage container" that simulates a real disk, enabling flexible, efficient, and isolated data management without needing additional physical hardware. Virtual disks are commonly used in virtualization, backup solutions, and testing setups to improve resource utilization and flexibility.
