Support for largefiles start in Solaris 2.6 with the introduction of "largefiles", a largefile, in 2.6 indicates a file that has a size between 2GB and 1Tb (terabyte), 1 Terabyte is the file size limit for Solaris 2.6, on a 32-bit system, a largefile is any file equal to or greater than
2GB: Solaris 2.6/Solaris 7 and Solaris 8, max filesystem size is 1 Terabyte, many reports that max file size will be 1 TB also, but a single file in Solaris 2.6/7/8 is limited to "about" 800 GB because the file must fit inside a file system, the file system is nominally 1 TB, but in fact one must create enough overhead in such a large file system
that the largest single file ends up being "about" 800 GB.
