Let us consider a file system which uses inodes to manage files on disk where each inode consists of a file name of four bytes, user id of two bytes, three timestamps of four bytes each, protection bits of two bytes, a reference count of two bytes, a file type of two bytes, and the file size of four bytes. In addition to that, the inode contains 13 direct indices, 1 index to a single indirect block, 1 index to a double indirect block, and one index to a triple indirect block. Each of these indices is 4 bytes. The file system also stores the first 356 bytes of each file in the inode. A disk sector is assumed to be 512 bytes and that each indirect block fills a single sector. What is the maximum file size for this file system?
