File allocation using I nodes.

This method is used to decrease the size of the table in the above method. Every file will have an I-node list. Allow a file have 15 pointers after that the first 12 pointers can be used to point to the blocks directly. The next three pointers are able to be used to point to indirect blocks. The first two point toward single indirect blocks. The single indirect block is an index box containing not data other than the addresses of blocks that contain data and the last pointer points to a double indirect block which contains the addresses of blocks that contain pointers to the actual data blocks.
