A flash memory management method for effectively deleting a file and a flash memory system, the flash memory system including: a flash memory; and an interface determining whether a sensed sector write operation instructs a file system to delete a file by examining metadata of the file system and deleting data in the flash memory corresponding to the file if the sensed sector write operation instructs deletion of the file. Accordingly, an interface layer between the flash memory and the file system can prevent unnecessary data from being copied in a future garbage collection process by recognizing a delete operation of the file system and quickly performing a future rewrite operation since actual data blocks are erased in file deletion.
