Abstract
A computing device executing a file system maintains a search tree that includes extents for managing first regions of unallocated storage space and bitmaps for managing second regions of unallocated storage space. For each region of unallocated storage space, the file system determines whether to manage that region using an extent or a bitmap based on one or more space management criteria.
