Note

A sparse file is a file that has one or more data areas that have not been allocated in it. A program will see these unallocated regions contain bytes of zero value, but these zeros do not use any disk space. All data with meaning or nonzero data is allocated, while all data has no meaning (large data series including 0s) are not allocated. When a sparse file is read, the allocated data returns as stored and the unallocated data is returned, by default, as zeroes (based on the specification of the claim. Secret C2). Sparse file support allows data to be allocated from anywhere in the file.
In a sparse file, a large range of zeros may not require disk space allocation. Space for nonzero data will be allocated in case the file is recorded (if needed).
The operating system recognizes files with ranges containing zeros only when they are compressed or sparse.
