11 .sp
12 .LP
13 A \fIlarge file\fR is a regular file whose size is greater than or equal to 2
14 Gbyte ( 2^31 bytes). A \fIsmall file\fR is a regular file whose size is less
15 than 2 Gbyte.
16 .SS "Large file aware utilities"
17 .sp
18 .LP
19 A utility is called \fIlarge file aware\fR if it can process large files in the
20 same manner as it does small files. A utility that is large file aware is able
21 to handle large files as input and generate as output large files that are
22 being processed. The exception is where additional files are used as system
23 configuration files or support files that can augment the processing. For
24 example, the \fBfile\fR utility supports the \fB-m\fR option for an alternative
25 "magic" file and the \fB-f\fR option for a support file that can contain a list
26 of file names. It is unspecified whether a utility that is large file aware
27 will accept configuration or support files that are large files. If a large
28 file aware utility does not accept configuration or support files that are
29 large files, it will cause no data loss or corruption upon encountering such
30 files and will return an appropriate error.
