ABSTRACT:
The present invention optimizes storage of stream file by dynamically adjusting the size of new extents. In one embodiment, a file system manager collects usage statistics for a plurality of files in a file system. The file system manager uses the usage statistics to create larger extents for frequently used files than for infrequently used files.
