It's not clear from your post, if you have deleted the files with WinSCP from your server.
For that see Can I undelete remote file removed with WinSCP?

Or if by "from WinSCP" you actually mean "from the server". I.e. that the files got deleted from the server without use of WinSCP. Though even than the above link applies to some degree.

Hi, could someone advise on how to recover deleted files and folders from WinSCP. The folder got deleted around 6 pm today.
Any help on this will be highly appreciated, thank you!
