Abstract
A virtual media (VM) method for mounting a folder stored in a storage device of a client for accessed by a server as a virtual drive. The client assigns virtual cluster indices to each file in the folder, and creates a file-cluster index table to store the assigned virtual cluster indices. The client also creates a VM file system complying with the FAT file system standard except that only subdirectories and no data files are stored in the VM FAT file system. The VM FAT table uses virtual cluster indices rather than actual cluster indices. Data written by the server are stored in a temporary data area without modifying the actual file system of the storage device. The virtual sectors requested to be written are “dirty”, and the dirty sector numbers and corresponding temporary sector numbers are stored in a dirty sector index table for use in a write-back step.
