Abstract: A system and method for managing files in a flash memory. The flash memory has a first storage area and a second storage area for storing files. Each of the files has a file header and a data block. The method includes writing the file header of each of the files into the first storage area and setting the first storage area as a first mode, writing the data block of each of the files into the second storage area and setting the second area as a second mode. Responding to the data block of one of the files being completely written into the second storage area, a memory address of the data block stored in the second storage area is written to a corresponding file header.
