How to upload files from local Windows UNC path (outside project root) to S3

Hi,
I have files on a Windows Server which I want to upload by cronjob to my Managed Server (nodejs) or S3 bucket.
The path of the file is in a database.
My thinking was to use my local NodeJS Webserver which is in the same local Network.

I found the following information on stackoverflow:

What should I think about if I try to implement this with Wappler?

Should this work?

At the moment I use a script with ftps for uploading the files. It does work but I would like to optimize the workflow.
