From: underh20 on 18 May 2010 18:10 Hello, What is the maximum number of files allowed in a directory under UFS in Solaris 10 ? What is the maximum number of files allowed in a directory under Veritas File System 5.0 in Solaris 10 ? I'd like to know where to locate this maximum number under UFS and Veritas File System 5.0 in Solaris 10. Is there any way that we could modify this maximum number ? Thanks, Bill

What problem are you trying to solve??

I do know that it's a very poor idea to put thousands or tens of thousands of files in one directory. Performance, to put it bluntly, will suck! |
