A file management apparatus capable of inhibiting an accessing operation for a plurality of areas within files. The file management apparatus includes a memory storing files each having multiple areas, a first storage unit for storing lock data denoting a locking condition of an accessing operation for each of the files, a determination device for determining whether the accessing operation for areas to be accessed is inhibited by referring to the lock data for the files, and an accessing device for accessing a particular one of the areas when the determination means determines that access to the group of areas containing that particular area is not inhibited. The file management apparatus also determines the inhibited/non-inhibited status for data areas within each file based on lock data and key data corresponding to each of those data areas.
