    The maximum size of size_t is provided via SIZE_MAX, a macro constant which is defined in the <stdint.h> header (cstdint header in C++). size_t is guaranteed to be at least 16 bits wide. Additionally, POSIX includes ssize_t , which is a signed integer type of the same width as size_t .

  5. File size - Wikipedia

    en.wikipedia.org/wiki/File_size

    File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte . A large value is often expressed with a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ).

  7. Large-file support - Wikipedia

    en.wikipedia.org/wiki/Large-file_support

    In 1996, multiple vendors responded by forming an industry initiative known as the Large File Summit to support large files on POSIX (at the time Windows NT already supported large files on NTFS), an obvious backronym of "LFS". The summit was tasked to define a standardized way to switch to 64-bit numbers to represent file sizes. [1]

  9. Data compression ratio - Wikipedia

    en.wikipedia.org/wiki/Data_compression_ratio

    Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
