A virtual disk management system used in a diskless PC network communication agent system consisting of storage media, storage servers and a user-end computer for creating virtual disks having a dynamic space allocation function at the storage media and storing data into and fetching data from the virtual disks. The virtual disk management system uses a physical block index table, a storage media group record table, a virtual disk physical block occupation table and a differential disk relation table for virtual disk control, allowing physical and virtual space address translation to be done at one time to improve virtual disk access performance.
