Working with an application that is very report intensive (100+).

Anybody have any pointers or suggestion for accomplishing this task?

Working with version 4.5
Using text files as database
Have defined the text files through ODBC Admin
Crystal updated odbc.ini, qetxt.ini when these were first created.

Anybody been through this process and want to help save me some headaches?

Thanks for you time
