A method and a system for implementing a duplex memory file system under distributed network environment are provided to improve performance in comparison to a method using an existing disk by implementing the main memory based file system. A memory file system library(120) receives a request for access to a file system from a user application program process(130). The memory file system library accesses the memory file system installed in a main memory(160) to perform works corresponding to the access request of the user application program process. If the work corresponding to the access request of the user application program process is memory file system change work, the memory file system library performs the change work in a disk(150) synchronized with the memory file system.
