A "Virtual Drive" is a software-based storage solution that simulates a physical hard drive on a computer. It allows users to store, access, and manage files without needing a physical device. Virtual drives can be created using various applications and are often used to mount disk images, such as those from ISO files, enabling users to access their contents as if they were on a real disk. These drives can enhance productivity by providing additional storage space and enabling easy file sharing. They are commonly used in cloud computing environments, where data can be stored and accessed remotely, making it convenient for users to work from different locations.
