OK, I'll consider this.
Before posting, please read how to report bug or request support effectively.
Bug reports without an attached log file are usually useless.
Particularly because it's the same problem with files search.
In my most updated version (v.5.13.3) the search functions still seems to be buggy.
Independent from the option 'recurse' or 'not recurse' WinSCP needs to even one second to finish a root search (file mask: e.g. "share/"; Search in: "/") with NO result although there are SEVERAL folders called 'share' on my server.
Please let me know why the search feature is definitely not working here (my Windows 7 computer).
Thank you so much.
