DESCRIPTION

9       A large file is a regular file whose size is greater than or equal to 2
10       Gbyte ( 2^31 bytes). A small file is a regular file whose size is  less
11       than 2 Gbyte.

13   Large file aware utilities
14       A  utility  is called large file aware if it can process large files in
15       the same manner as it does small files. A utility that  is  large  file
16       aware  is  able  to  handle large files as input and generate as output
17       large files that are being processed. The exception is where additional
18       files  are used as system configuration files or support files that can
19       augment the processing. For example, the file utility supports  the  -m
20       option  for an alternative "magic" file and the -f option for a support
21       file that can contain a list of file names. It is unspecified whether a
22       utility  that  is large file aware will accept configuration or support
23       files that are large files. If a large  file  aware  utility  does  not
24       accept  configuration  or  support  files that are large files, it will
25       cause no data loss or corruption upon encountering such files and  will
26       return an appropriate error.
