>Thanks for the advice, Craig. The files aren't opened individually, as in use xyz in 0 order abc, etc, but they are all set up in the Data Environment, with a complicated set of links between them. The files aren't huuuuge, with the larges having 65k records, and the others ranging down to just a few. There are 24 files, and it can take up to 15 or 20 seconds to load up...

The dataenvironment will open them individually, in the order defined by ZOrder. It's just automated.
