So when does the problem occur?
When I double click the site i am having problems with, the session opens well.
Thanks for your report.
WinSCP 5.5 can definitely open sites two folders deep in general. So there has to be something specific about your setup. What actually happens when you double click the site you are having problems with?
It was possible to open sessions of type folder/subfolder/session with 5.1.7 version but not with latest versions.
I can just open sessions of type folder/session but i don't want to change my winscp.ini file. Is there any solution ?
