I want to use the MV command to GET files from a unix host to the local windows server, winscp is running on the windows server. There will be two servers running the retrieval process in parallel for redundancy, but I don't want both servers to try and move the same file.

I can't find anywhere in the documentation that describes whether winscp will put a lock on the source file on the unix server and if other winscp sessions will honor that lock if they see it.

Thanks

There's no lock. But you can do it like this:
- first move files that are there to different temporary remote directory, specific to retrieving machine (e.g. /tmp/retrieve1 and /tmp/retrieve2)
- download files from the temporary directory
Btw, mv command is for the first part (moving between two remote directories), to move files to local directory, use "get -delete".
