I do not think you can make IIS provide the ownership information.
Hi I am using WinSCP for quite a long time mostly against Synology SFTP servers and I am happy with its functionality.
Last month I have installed Win 2012R2 server and I am running FTP server with implicit TLS/SSL and found following issue:
In WinSCP klient I am not able to see owner/group of the files. Even opening Properties for file does not show anything.
There are 2 options on Windows 2012R2 IIS FTP server for directory listing:
MS-DOS - with this selected WinSCP shows all blank (there is nothing - group/owner/access rights are empty)
UNIX - this shows Owner as "owner" and Group as "group" (not very helpfull) :D
Any idea how to fix this?
