That's one way.
If you want to do it completely from command-line, specify the remote directory as part of session URL:

Hi everybody

I found the solution.

I must create a session in interface GUI and save it (for example PHIPHI ).

I declare the folder in the menu Environnement / Directory. See attached picture.

Then I launch the command in DOS (cmd )
winscp.exe PHIPHI

Hello

I would like launch WinScp with interface GUI on remote directory in a batch file.

For example

1)
Folder1.bat
winscp 192.168.0.100 remoteDirectory:/Public/folder1

2)
Folder2.bat
winscp 192.168.0.100 remoteDirectory:/Public/folder2

Thank's
Phil
