When I try open this folder WinScp begin counting files and after 3000-4000 files its broken. And I lost connection or see empty folder without .. in top. And after than WinSCP don't work with ftp account. So it need close.
I think if this program can't show list of many files, why program try to show it? It need show first 1000 files, and show some button. If we push this button we can see one more 1000 files etc.
