Multithreaded file copy

2006-01-08 10:31

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

2006-07-19 10:43

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.

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/parallel 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).

@Klaus_1250: WinSCP supports that. See https://winscp.net/eng/docs/transfer_queue

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

@Klaus_1250: You cannot do that from console. However you can run multiple instances of WinSCP console in parallel.

Edit 2023: Or use .NET assembly.

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.
