It is currently possible to create filesystems as large as 2^40 bytes (1TB). A single file can thus consume up to 1TB of disk space.
The capability to create large files and filesystems is intended for specialized applications that need to deal with more than 2GB of data in a single file. General users will most likely never need to use this capability.
The following set of system utilities have been made large-file aware, and a notice stating that has been added to each manual page. See Intro(2) for more information.
