Abstract
A system and method for allocating contiguous portions of memory to a file. On or more file nodes are provided for allocating memory to one or more files, and the location of these file nodes is maintained. Within these file nodes, the location of one or more runs of contiguous portions of memory are maintained. These contiguous portions of memory are allocated to a file in accordance with the corresponding file node. In one embodiment, the file nodes can be extended in a binary tree structure of additional nodes each storing locations of runs of contiguous portions of memory.
