ABSTRACT:
A system and method for managing a mobile file system cache to maximize data storage and reduce problems from cache full conditions. Cache management automatically determines when the space available in the cache falls below a user-specified threshold. The cache manager attempts to free space needed for caching the next object. Files are deleted from the cache if no server updates are pending and if such deletion will provide the needed space. If automatic deletion does not provide sufficient space, the user is prompted for action. The system user can control the cache by increasing or reducing its size and drive allocation and can explicitly evict clean files from the cache. Cache expansion can be to logical or physical storage devices different than those on which the original cache is stored. The system enables separate storage of temporary files allowing identification and deletion of such files.
