FileIO 2 builds upon and improves the FileIO Library in many ways. You can still use FileIO 2 in the same way that you use FileIO, by editing your text file layouts by hand. But with FileIO 2 you also have the option of managing your data files and your file layouts through a powerful Web Interface.
Additionally, FileIO 2 stores your file layouts in BR internal data files, making them easily extendable. If you want to keep track of additional information in your file layouts, you can do so with FileIO 2 easily.
Another nice benefit of using FileIO 2 is that its fully compatible with ODBC.
See the article on the FileIO Library for more information.
