For a start, you need this:
https://winscp.net/eng/docs/commandline#syntax
(the part about doubled double quotes around parameters with spaces)

I gave the complete command line, but it didn't work! If you want to upload files to the Program Files directory, how should you modify them?

I do not understand your question.
What problem do you have?

【 winscp.exe /console /command "option batch continue" "option confirm off" "open sftp://admin:admin@192.168.0.12:2121" "option transfer binary" "put C:\Users\Administrator\Documents\wordpad.exe /C/Program Files/Windows NT/wordpad.exe" 】
This is the command line I use, but no, I don't know how to write it.
