How to view what files were deleted

I accidentally deleted files from my remote server. I don't know what files were deleted as it was deleting a directory containing thousands of files. I have been searching for over an hour on how to do this and no one seems to comment on it. All I want to know is what files were deleted, I do not care about recovering them. I dont even understand how to view the log? This interface is very confusing.

Did you have logging enabled? If not, there's no way to see the deleted files. At least not in WinSCP. Your server may have a record of the deleted files (though it's not sure). But for that you would have to contact your server administrator.
