ABSTRACT:
An apparatus for file system management includes a non-volatile storage device, a volatile memory device, and a processing unit. The non-volatile storage device stores a file containing actual file content. The volatile memory device storing physical file handle context comprises a pointer to the beginning of the actual file content. The processing unit receives a virtual file generation request with a physical file handle corresponding to the physical file handle context, and mapping information of a segment of the actual file content, and generates a virtual file name including the physical file handle and the mapping information.
