File Size

File size measures the size of a computer file. Typically it is measured in bytes with a prefix. The actual amount of disk space consumed by the file depends on the file system. The maximum file size a file system supports depends on the number of bits reserved to store size information and the total size of the file system. For example, with FAT32, the size of one file cannot be equal or larger than 4 GiB. Some common file size units are

  • 1 byte = 8 bits
  • 1 KiB = 1,024 bytes
  • 1 MiB = 1,048,576 bytes
  • 1 GiB = 1,073,741,824 bytes
  • 1 TiB = 1,099,511,627,776 bytes

Famous quotes containing the words file and/or size:

    A common and natural result of an undue respect for law is, that you may see a file of soldiers, colonel, captain, corporal, privates, powder-monkeys, and all, marching in admirable order over hill and dale to the wars, against their wills, ay, against their common sense and consciences, which makes it very steep marching indeed, and produces a palpitation of the heart.
    Henry David Thoreau (1817–1862)

    There are obvious places in which government can narrow the chasm between haves and have-nots. One is the public schools, which have been seen as the great leveler, the authentic melting pot. That, today, is nonsense. In his scathing study of the nation’s public school system entitled “Savage Inequalities,” Jonathan Kozol made manifest the truth: that we have a system that discriminates against the poor in everything from class size to curriculum.
    Anna Quindlen (b. 1952)
