sync timing issue

I'm syncing from remote(ftp server) to local(windows share), one-way only. Is there anyway to prevent sync on remote files that haven't finished uploading to the ftp server yet? I'm using the file size criteria currently to have it re-download the complete full sized file. I know I am causing this issue myself by running the script every hour, but I have enough data being uploaded to my FTP server to justify that, so is there any solution other than just don't run it before I know the data is fully uploaded.

There's generally no way to detect that a file has not been finished uploading yet.

Gotcha, thanks for the information.
