Edit 2023:
In scripting, use -resumesupport switch or put/get/other commands.
As the documentation says:
https://winscp.net/eng/docs/ui_pref_resume#temporary

Thanks, for the hint.

But I'd like to disable temporary filename via command-line options too.
I didn't find any info on the page https://winscp.net/eng/docs/commandline.

Thanks in advance!

Please read documentation:
https://winscp.net/eng/docs/ui_pref_resume#temporary
If that does not help, come back.

Hello,

is it possible to store a file on the remote SFTP-server without a temporary filename (extension .filepart).

Thanks!
