Linux has gained more and more widespread acceptances for its open source code. The programming for the file system of Linux becomes the most popular and the most critical applications. By the analysis of the source code of Linux's file system, not only the layout of the hard disk in the EXT2 file system but also the data structures related to EXT2 file system such as supper block, group descriptors, inode and directory structure detailed are described.
