It has to do with how unix and file systems are constructed. In Linux
the next block in a file is found through inodes containing 13 (If I
remember correctly) pointers that either to a block of the file or
another inode that has 13 pointers, which leads to indirect access to
the next block. I think 2 levels of indirection are allowed. defraging
such a system is not meaningful.
