We've encountered similar problems here but not to that degree. 1-2 million
files is nuts.
The best solution I've seen is splitting up the files into manageable chunks
and making each one a separate stream, but that can have it's own issues if
it's a dynamic file list. Sounds to me like the application design team for
this server didn't consider a few things. Windows is notorious for its
dismal performance with a large number of small files, 3-4 times worse than
Unix.

Subject: [Veritas-bu] Millions of files in one directory
Hello,
We have a client that is failing because there are too many small files in
one directory. There are apprx. 1 - 2 million files in two different
directories that are causing the failures. The system is a Win2k server
using NetBackup 5.0, master and media servers are also Win2K with NBU 5.0.
Has anyone had this problem and found a good resolution?
Thanks,
Kris
