Abstract
Disclosed is a file accessing method of a file system which manages data by a block unit of a fixed size having an index and provides information associated with a file via a plurality of entries having an index and linked information of each of blocks forming the file. The file accessing method includes providing a hint information area to each of the plurality of entries so as to record an access mode or continuous allocation information for the file, allocating the plurality of blocks to record contents of the file, and recording the access mode in each of the hint information areas of entries corresponding to a first chain group of the allocated blocks and the continuous allocation information in the hint information area of at least one entry corresponding to a second chain group of the allocated blocks.
