I too faced this problem, but I don't know about the synchronize command. With the help of your thread I gained some knowledge about it. What are the commands should we used for complete resume download without time delay?

Thanks :)

That's configurable (in GUI):

And I guess when the computer reboots in the middle of the transfer it won't resume, since it would require to run the script all over again.

Correct.

So, if my connection dies, it should resume? Or if the computer restarts?

No, it's not possible.

Oh, i see.
And any chance it could be implemented in future versions?

No, it's not possible.

Hi :)

I was wondering if there was a way to get WinSCP to resume a file download using the 'synchronize' command. I mean, when I use the 'get' command and the download of the files stops in the middle of the download(like 1.2GB out of 1.9GB), then I can run the script again and the download will continue from 1.2GB upwards. Now, when using the 'synchronize' command(with -criteria=size), the download will start all over again if the files aren't of the same size.
So, is the any way to do it? Cause with large files, it's really depressing having to start the download all over again...
