Is there anyway to change the maximum number of allowed sub directories in a directory for unix.

Because I found the maximum to be around 20,000...

Which unix?

In HP-UX there's a tunable value of VX_MAXLINK which may be sent between LINK_MAX and INT_MAX -- though to only about 65k.

In Solaris it's set to a 'signed short', so you won't exceed ~32k. (32768)

I have to ask; why in the world would you want to exceed that limit? You understand that parsing that many subdirectories puts a serious strain on the load factor ... this wouldn't be a software delivery system application, would it?

In any case, if at all possible, limit your directory structure as much as possible.

Cheers.
