Help! Recover deleted folders in WinSCP

I made a big mistake. :shock: I deleted a complete folder in my remote directory. I am using SCP and explore-style.
Can I recover that folder? The data is storaged in another place? I hope that there is a solution.
Thank you for your help.

WinSCP makes backups only if you have enabled remote "recycle bin" on environment tab of login dialog.
There is also chance that the server does backups itself, but I doubt.
