Multithreaded file copy

I'm not sure if WINscp supports multithreaded file copy. I mean the way prozilla does for fast copy.
If not, please consider if we can have that feature too.

Multithreaded file upload

This is something urgently needed. we need it because there are some huge uploads which are needed with generally slower upload speed (512KBPS)ISPs.

Faster file transfers

Ditto. I am frequently needing to transfer data files upwards of 2 GB from Europe to North America, which is painfully slow without multi-threaded file transfer.

Re: Multithreaded file copy

Do you mean to transfer parts of one file using parallel connections?

Yup. Would really be a nice feature, though I'm personally more interested in concurrent/parralel down/uploads of different files. I usually need to up-/download large batches of small files and only a small portion of bandwidth is currently used (for large files, I'm able to attain maximum transfer speeds).

WinSCP supports that. See documentation.

How do I do that in batch/console mode? I've automated it in Perl, which calls WinSCP with a dynamic batch file. I fiddeled with the background transfer settings (enable by default and upped the number of connections) but never got it to work (apperently) in batch/console mode.

You cannot do that from console. However you can run multiple instances of WinSCP console in parallel.

I would much rather see that build-in in WinSCP. Running multiple instances of WinSCP in console/batch mode is less efficient than one instance of WinSCP using parallel connections or more than one SSH connection. I think it would be a much appreciated feature for WinSCP.

Even WinSCP opens multiple SSH connections for parallel transfers.
