Hi All,

i got few questions...

1) What is the maximum number of files that we can save under a single directory in AIX ? (* we have enough storage/disk space)

2) And what is the maximum number of sub - directories in side a directory?
I know that...every directory is a (special) file...so if i get answer for my 1st qn....it will answer 2nd qn too. * correct me if i'm wrong

Any idea is highly appreciated.

we don't have any limit for JFS2.(dynamic allocation of i-nodes) as long as we've enough storage.

Thanks for your reply though!

The limit to the number of files in JFS2, or the number of files within a directory, depends on how much space you have and the size of the files.  I'm going from my memory, but I believe you can create as many files as you have space for.  The JFS2 max file system size is 32 TB.   The smallest file in JFS2 can reside in a minimum of a 512 byte sector on disk.  

So basically you can have as many as can fit.  If you need to know the exact number, I'd suggest creating a vary small file system with an outline log, and creating as many 1 byte files as you can until you get an error.
