Abstract: An electronic device may include a storage, a memory, and a processor configured to read or write a file from or to the memory. The memory may include a lower file system for compressing and storing a file by using a first partition of the storage and an upper file system for decompressing and storing a file by using a second partition of the storage and/or the lower file system. The processor may copy, to an upper file system of the memory, a first file having an access number greater than a certain level by decompressing the first file in the lower file system, and may control a stackable file system to read the first file from the upper file system and to provide the first file to the application layer based on a request from the application layer being detected with respect to the copied first file.
