I tired adding the local and it connects but then brings up the synchronize dialog box and I have to click on ok. How can I automate this so it is un-attended?

You have to specify local directory before the remote one. Also I would recommend using scripting instead.

I'm trying to create a batch file that will get the all the files in a remote server and download them to my local directory. I just need all files in the remote dir.

It's says "no differances found". Here's my command line. I get logged in fine.

winscp.exe sdm /synchronize /incoming/BRIAN /defaults

Can anyone help
