    Abstract: Disclosed is an electronic device comprising: a non-volatile memory configured to store at least one file including metadata and user data; a file system configured to manage the at least one file through a log stream; and a file system (FS) manager configured to monitor a free space log included in the log stream corresponding to a first free space of the non-volatile memory, and to transmit a compression request to the file system based on the size of the first free space, displayed on the free space log, having a value less than a first reference value. The file system may be configured to: based on the compression request being received, compress at least a part of the metadata stored in the non-volatile memory based on the log stream, to store same in the first free space; and display a second free space of the non-volatile memory, secured through the compression of the at least a part of the metadata, as a reserved block log in the log stream.

    Abstract: An electronic device in an example embodiment may include a communication interface configured to receive an original file, a memory, and a processor. The processor may generate bit information corresponding to uppercase and lowercase letters included in a filename of the original file. The processor may generate a case insensitive (CI) filename in which the filename of the original file is expressed by characters of a first type. The processor may encrypt the CI filename and may calculate a first hash value corresponding to the encrypted CI filename. The processor may record filename metadata including at least one of the encrypted CI filename, a length of the encrypted CI filename, the first hash value, and the bit information, in the memory. The processor may search for a target file to be found based on the filename metadata.
