[Q] Unix Maximum file size, the max number of file and directory


I want to know the maximum size of the file, and the maximun number of the file or directory in Unix(Solaris)..

1 Solution
I'm not 100% on these numbers, but I'm pretty sure it's somthing like:

Traditional SunOS (aka Solaris 1.x): 2gig max file size, 2gig max filesystem size (might have been 4 gig on later releases), and ~64k files/filesystem.

Early 2.x releases with BigFiles support in the filesystem: 2 gig max file size, 2^64-1 max filesystem size, and 2^32-1 files/filesystem.

Recent 2.x releases (i.e., 2.7): 2^63-1 max file size, 2^64-1 max filesystem size, and 2^64-1 files/filesystem.

The bottom line is that these maximums are essentially infinite in 2.7.
