Very Large File Downloads

We use WinSCP (version 5.19.2) via command lines in PowerShell scripts to download very large (multiple GB) files via FTP. It appears to hold the whole file in system memory as it is downloading and so we hit intermittent system memory errors when multiple processes are running. Is it possible to set up WinSCP so that it streams large files directly to disk rather than holding it in system RAM?

I don't see that happening with WinSCP by default. RAM usage isn't going up and the OS shows storage usage during transfer.

Maybe its related to how the OS is setup or something? I can only think of some most likely not used here situations like a RAM disk.

I would expect here instead that those memory errors be just a coincidence and you have something else going on.

At least that's what I get from your post. Maybe Martin will see something different?

Please attach a full session log file showing the problem (using the latest version of WinSCP).
