Just by unchecking the "Show home folder as root" option in the user account settings on WS_FTP Server.

No really... SFTP protocol spec requests client to "canonify" the remote path it assembles from pieces (like current directory and its subdirectory) using SSH_FXP_REALPATH request. It then needs to use the returned path instead the one it assembled. Your server fails that request, so WinSCP has not way to access the folder you want.

I can only guess why others do work. Maybe they ignore the error and they use path they assembled instead of the canonified one. Or they just ignore the requirement a do not even try to canonify the path.

Maybe because WinSCP follows the SFTP protocol specification, while the others do not? :)

I do not know how to help you. I looks like a server-side problem to me. Please ask on Ipswitch support.

Hello,

I have an Ipswitch WS_FTP server with SSH installed.
On this server you can create some virtual folders, and when the user connect to the server, he will see only the where he had access.
When the user access one of these directories, he will see the content of the fizical directory.
Maybe some of you work with this type of server and understand what i say.
This works fine, but when I try to access one one sub-directory of this virtual folder, i receive the error message:

Cannot get real path for '/Virtual_Folder/History'.
General failure (server should provide error description).
Error code: 4
Error message from server: Folder not found: /Virtual_Folder/History
Request code: 16
realpath User Error 0 Error Folder not found: /Virtual_Folder/History

Using PSFT, and FileZilla I receive the same error but it work.
Using WS_FTP Pro, as you may expect, it works fine, and I don't receive any error message.

My problem are not the error from the log, but that using WinSCP I cannot access the subfolders, and with other problems is working fine.

I'm using WinSCP 4.2.5.
I have tried also with other versions, 4.1.9, 4.2.3 but I receive the same error.
I'm using the GUI, but I have tried also from command line, same error.
