<p>Disclosed is a system that places a statistical collection routine (124), which tracks file usage, within the path lookup process (126) of an operating system (118). A statistic summarization process (Fig. 3) runs as a task of the operating system and periodically accesses the statistics collected (302) by the statistics collection routine and updates a database (310, 312). A file migration process (Fig. 4) is scheduled to run periodically to examine the database information. Files that have a predetermined usage during the time may be migrated (412, 414, 416), based on user criteria, between a primary, high speed, storage device (110) and a secondary, slow speed, storage device (112). The secondary storage device might be a network file server (130) attached to a local area network (115), a read-only device, or other storage device. <IMAGE></p> |
