An operation method for an electronic device is disclosed. The operation method for an electronic device according to an embodiment may comprise the steps of: configuring a block layer for virtualizing a storage on a volatile memory as a block device; storing a file in the configured block layer in units of blocks; selectively encoding, in a unit of at least one block, the file which has been stored in units of blocks; and storing at least one of an encoded block and a non-encoded block in the storage.

Selective encoding method and electronic device using same

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.

Electronic device for controlling file system and operating method thereof

A method is provided including: generating a virtual block device including a file allocation table area located in an internal storage of an electronic device, and a cluster heap area located in a memory card that is inserted in the electronic device; and mounting a file system of the memory card using the generated virtual block device.
