摘要：
A file system including: a first type storage medium; a second type storage medium; and a processor providing a file system using a first area in the first type storage medium and a second area in the second type storage medium, wherein the processor manages whether metadata is permitted to be stored in each of the first area and second area, stores a first file and first metadata of the first file in the first area, which is managed to permit storing metadata, migrates the first file stored in the file system to the second area, which is managed not to permit storing metadata, and changes the first metadata stored in the first area to point to a location of the first file in the second area.
