It will cause a small memory leak as strings aren't freed until app exit but I don't believe it will cause further problems. If for some reason it does, that routine is part of the high performance loader, to disable: in the Properties in the form designer for the control, set HighPerformanceMode to False. The performance difference is negligible until you reach thousands of files in a folder, and then only more then 2-3s when you reach the tens of thousands.

I'll look into this issue, thanks for letting me know.
