Test if upload is enabled without a file

Hellooo,

I want to test if an SFTP server is read-only or accepts uploads.

The first thing that comes to mind is of course to upload a file and see if it returns an error however I do not want to have to create a dummy file to upload.

Is there any way to feed a variable or otherwise trick $session.PutFiles instead of using an existing filepath or is there any other way to solve this?

There's no API in SFTP protocol that could by used by WinSCP (or anything else) to test, if the server is read-only.
