A sparse file is a type of computer file that attempts to use file system space more efficiently when blocks allocated to the file are mostly empty. Windows OS, particularly with the NTFS file system, supports sparse files, which allow the allocation of hard disk space only for meaningful (non-zero) data. This helps in conserving disk space by not allocating blocks for regions that are empty.

correct
A> Support for sparse files is introduced in the NTFS file system as another way to make disk space usage more efficient. When sparse file functionality is enabled, the system does not allocate hard disk drive space to a file except in regions where it contains nonzero data.
A > The sparse files offer a technique of saving disk space by allowing the I/O subsystem to allocate only meaningful (nonzero) data.
