Background transfers with a script

Hi
I am uploading a large number of small files using FTPS via a script, once a week.

I am trying to find how to select background transfers with the script.

Using the GUI:
Preferences/Transfer/Background/"Transfer on background by default"

With the setting off the GUI speed matches what I am getting using a script.
With the setting on, the GUI speed is approximately 10 times faster.

Currently it takes 20 hours for 100,000 files with the script.

Scripting does not support parallel transfers.
Though see https://winscp.net/eng/docs/library_example_parallel_transfers

Thank you very much for your quick reply.

So far I've avoided C#, powershell, etc, using only Windows CMD batch commands - I haven't coded properly for 20 years.
Although I can probably extract the relevant features from the code you linked to, it seems like the proverbial "sledgehammer to crack a nutshell".

Currently it only requires a few lines, which works, albeit slowly, even for a nested directory structure.

e.g.
open ftps://!Login! -rawsettings FtpForcePasvIp2=0 SendBuf=0 SshSimple=0 -explicit
put -delete -resume -noPreserveTime -transfer=binary TEMP\*.* %RemoteFolder%/ARCHIVE/

Can it be requested as a future feature?
It seems like fairly fundamental functionality.

Thanks for your help

Sure we will consider it.
Though it's the proverbial "Pandora's box" :)
