Abstract:
1. A management system for monitoring capacity change of a data storage device and for adjusting file system capacity and file system structure and contents of a file system located on said data storage device when capacity of said data storage device changes said file system includes a file allocation table which must immediately be followed by a file data region for correct operation of said file system said file data region stores data belonging to said data files the system comprising: a. a logic unit capable of altering parameters and structure of existing said file system containing data files in a manner that adjusts said file system storage capacity leaving said file system and said data files consistent said file system structure is adjusted by said logic unit in a manner that said file allocation table size changes keeping said file allocation table appear to be followed immediately by said file data region, b. a monitoring unit for indicating when change in storage capacity of said data storage device occurs, whereby said monitoring unit indicates a change in storage capacity said logic unit changes parameters and structure of existing said file system according to said indication of storage capacity change said logic unit may expand or shrink said file allocation table according to change of storage capacity of said data storage device independently by said data storage device keeping said file system consistent for file system operation and keeping said file system capacity updated following said change in storage capacity.
