Abstract
A journaling file allocation table (FAT) file system includes an FAT file system module, a storage device and a driver. The FAT file system module includes a journaling module and receives a file operation instruction sent by an operating system. The storage device has an FAT file system and an FAT journaling cache. The driver is coupled to the FAT file system module, the journaling module and the storage device in order to access the storage device. When the FAT file system stored in the storage device is a journaling FAT file system, the FAT file system module enables the journaling module to receive and execute the file operation instruction sent by the operating system and to accordingly produce a corresponding file operation instruction to the driver for performing a journaling file operation on the storage device.
