Version 8.0 Export to Crystal (RPT) Format Error

[SupportSystems]

I am having trouble exporting a report, any of my reports, once the number of files in a particular directory gets above 2.1 million or so. Our system writes out and compresses all saved output to a directory whose structure is specific to a day. Once the number of files in the folder gets above about 2.1 million, an error 997 is returned - an overlapped I/O operation - to the application. We are running Version 8.0 crpe32.dll called from our application to run and export the reports. If run from the developer, no message is returned but the report is not written out. If no other changes are made and some files are moved to bring the total number to about 2 million things work normally. This process has been in place for years and has been unchanged for the past three months. The server is Win 2000, desktops are Win 2000 pro.

Thanks for ANY help!!
