1. A data arrangement method based on file system, adapted to a rewritable non-volatile memory module, the rewritable non-volatile memory module comprising a system region and a storage region, and the data arrangement method comprising:
analyzing a file system stored in the system region to obtain a plurality of first logical units to which a first file belongs and first distribution information of a plurality of first physical units in the storage region, wherein the first physical units are mapped by the first logical units;
determining whether to activate a data arrangement operation on the first file according to the first distribution information;
reading first data belonging to the first file from the first physical units after the data arrangement operation on the first file is activated; and
sequentially writing the read first data to at least one second physical unit in the storage region.
