13 13 A \fIlarge file\fR is a regular file whose size is greater than or equal to 2
14 14 Gbyte ( 2^31 bytes). A \fIsmall file\fR is a regular file whose size is less
15 15 than 2 Gbyte.

19 19 A utility is called \fIlarge file aware\fR if it can process large files in the
20 20 same manner as it does small files. A utility that is large file aware is able
21 21 to handle large files as input and generate as output large files that are
22 22 being processed. The exception is where additional files are used as system
23 23 configuration files or support files that can augment the processing. For
24 24 example, the \fBfile\fR utility supports the \fB-m\fR option for an alternative
25 25 "magic" file and the \fB-f\fR option for a support file that can contain a list
26 26 of file names. It is unspecified whether a utility that is large file aware
27 27 will accept configuration or support files that are large files. If a large
28 28 file aware utility does not accept configuration or support files that are
29 29 large files, it will cause no data loss or corruption upon encountering such
30 30 files and will return an appropriate error.
