Thanks Frank. I appreciate your feedback and understand the issue you raise. And since your post I have further increased the number of placemarks!

However, I did break the data out into sub folders by source and by type of report. It sounds like you are suggesting that even that may not be sufficient.

Of course, I also currently have all of the subfolders selected. I suppose I could deselect them for start up, but I was concerned that a novice who loaded the file might be confused if nothing showed up on the screen. Maybe some sort of compromise would be best.
