Portions of the local memory assigned to be shared by the first and second processors may be cooperatively accessed by each of the processors without intervention by the operating system. The coating apparatus includes: a table on which an object is located; a slit nozzle installed above the table and dispensing a coating solution on the surface of the object; an auxiliary coating device installed at least one end of the table; and a driving unit moving the slit nozzle in a predetermined direction. For each region of unallocated storage space, the file system determines whether to manage that region using an extent or a bitmap based on one or more space management criteria.
