Q. How is the NTFS namespace planned? Explain.
Answer: The NTFS namespace is prearranged as a hierarchy of directories where every directory uses a B+ tree data structure to store an index of the file names in that directory. The index root of a directory encloses the top level of the B+ tree. Every entry in the directory contains the name as well as files reference of the file as well as the update timestamp and file size.
How can an index file be used to speed up the access in direct-access files? Have an index in memory; the index gives the key and the disk location of its corresponding record.
