Dynamic Bitmap for Huge File System

In this paper we propose a new mechanism for file system using a dynamic bitmap assignment. While traditional file systems rely on a fixed bitmap structures for metadata such as super block, inode, and directory entries, the proposed file system allocates bitmap and allocation area depends on file system features. Our approach gives a solution of the problem that the utilization of the file system depends on the file size in the traditional file systems. We show that the proposed mechanism is superior in the efficiency of disk usage compared to the traditional mechanisms.
