Unable to upload and download file using SFTP

I’m trying to upload and download using “SFTP” activity and connection also showing OK but after successfully run file not uploading and downloading and not showing error during.
Can you suggest other way to upload and download files using sftp server in uipath
What is key file and pass phrase in SFTP Session?

Error screen shot please.

you can create a bat file and run, using Winscp tool

Can you please explain in detail?
or we need to add bat file in key of sftp activity?

My solution was to use WinSCP, and create scripts that can be run from UiPath.

With WinSCP it is fairly simple to create scripts, and I just run them with a command in cmd/ execute the bat file through start process (from uipath). This solution works, but requires more work.
