".archive" directory created after file upload

Hi Martin,
Hope you are doing well!
I've been using WinSCP for the last 7 years. It is the best tool out there.
Currently, I'm stuck on a problem which is,

I'm using your create script called "Uploading the most recent file"
URL: https://winscp.net/eng/docs/script_upload_most_recent_file
The script is working fine but mainly after uploading the files successfully, the file automatically moved to the .archive directory, which is wired, because inside the script nothing is mentioned for .archive directory creation. Could you help me with that?

See Why is uploaded file not showing in a remote directory or showing with a different name?
