Yes.
See https://winscp.net/eng/docs/scriptcommand_open#timeout

Hi. I have problem with WinSCP script based on sync. I have lot of files in source directory and it's running android (smartphone). Simply i just want backup some folders and files to my pc over wifi with ftp. Everything is nice, but lot of files in source directory causes timeout to server response and causes error messange "Could not retrieve directory listing" (because it's still loading files in that dir. btw,it's camera directory so pictures and videos). Can i fix it by changing server response timeout?
