Re: *Max4GB or *Max1TB

   All this is easier said than done when the client has no source code to
   the package. I'm having enough trouble convincing them that replacing
   their 400 package with an SQL Server solution. It's time to get them a
   trip to Rochester.

   I walked into a meeting with their IT staff this AM. I'm old enough to be
   the father of everyone in the room. Fortunately, I never spent any time in
   Indy during my mis-spent youth.  :-))

     Paul,

      I think you would be better off determining which access paths can be
     shared (subsets of the other) and then sharing those access paths. Then
     determining which Logical Files are not being used and delete them.  If
     you think about it, each time a write is done to the physical file, you
     have to go out and update those 250 logical file access paths.  That
     takes a lot of time.

      While you might get some improvement with changing from 4Gb to 1TB as
     the size, I think the number of logical files is the issue.

     Pete
