Recover deleted files

WinSCP 4.3.4
OS: Linux Redhat 5

I accidentally deleted a folder with some files (F8)
How can I restore it?

When I delete files with the F8 option, they will be permanently deleted or moved to the trash?

Please read FAQ:
Can I undelete remote file removed with WinSCP?

Thanks for the message.
But I can't see this option.

Advanced option is enabled.

Have you clicked Other settings > Recycle bin?

My ressourcen.cfg just disappear after I open it. How can I recover it?

@Carlos1111111: What exactly did you do? Can you reproduce the problem?
