Abstract: A method for initializing a storage is provided. The method includes comparing a size of a disk partition of the storage with a size of a filesystem image recorded on the storage, and reconfiguring the filesystem image in a dynamic manner if the disk partition size is larger than that of the filesystem image, wherein the filesystem image may include a metadata area composed of metadata blocks and a data block area composed of file data blocks, and wherein the data block area may include in sequence a first free block area composed of only file data blocks where data is not recorded, and a file data area composed of at least one file data block where data is recorded. Various other embodiments are possible.

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.

Abstract: An electronic device includes: a storage device including multiple segments configured to store data; a buffer memory configured to store segment attributes corresponding to the multiple segments, respectively; and one processor electrically connected to the storage device and the buffer memory. The one processor is configured to: determine, based on two or more parameters related to a data requested to be written, a data attribute; store the data requested to be written in a segment of the multiple segments, the segment being corresponding to the data attribute among the multiple segments; store a segment attribute of the segment, which is determined based on the data attribute in the buffer memory; update the data attribute, based on a data modification time of the data requested to be written; and update the segment attribute, based on the updated data attribute.
