Abstract
A method of operating an electronic device and the electronic device are provided. The method includes mounting at least one lower file system, which is configured to generate a file object managing a page cache, and mounting a highest file system, to which a virtual file system directly accesses, at a higher layer of a layer corresponding to the lower file system; in response to a file mapping request of a software program, generating a virtual memory area including a virtual address for a file corresponding to the file mapping request; and generating a first virtual address link between a file object of at least one lower file system having a page cache of a file corresponding to the file mapping request and the virtual memory area.
