Abstract

In this paper, we propose a new user-level file system to support block relocation by modifying the file allocation table without actual data copying. The key idea of the proposed system is to provide the block insertion and deletion function for file manipulation. This approach can be used very effectively for block-aligned file modification applications such as a compress utility and a TAR archival system. To show the usefulness of the proposed file system, we adapted the new functionality to TAR application by modifying TAR file to support an efficient sub-file management scheme. Experiment results show that the proposed system can significantly reduce the file I/O overhead and improve the I/O performance of a file system.
