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:

    While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.
    Barbara Howar (b. 1934)

    It is very considerably smaller than Australia and British Somaliland put together. As things stand at present there is nothing much the Texans can do about this, and ... they are inclined to shy away from the subject in ordinary conversation, muttering defensively about the size of oranges.
    Alex Atkinson, British humor writer. repr. In Present Laughter, ed. Alan Coren (1982)
