Abstract
A storage device implements a file profiling mechanism to minimize fragmentation. A plurality of files is organized according to a high or low read/write access frequency. A plurality of unchanging file types are placed in a first grouping. A plurality of oscillating file types are placed in a second grouping adjacent to the first grouping. A plurality of the high frequency read/write access files which are growing file types are placed in a third grouping adjacent to the second grouping. A remainder of the growing file types not placed in the third grouping is defragmented. The remainder of the growing file types is then placed in a fourth grouping adjacent to the third grouping.
