Answer 1

Welcome to SO!

There is no way to do what you're suggesting for security reasons. You don't have rights to choose where the file will go on their OS. JS won't go any deeper than the user's browser. What your asking for is essentially FS (file system) read-write permissions.

Make sure to do a little searching around before you ask new questions, as this one was already answered here: Directory Chooser in HTML page

If I understand your question correctly, then perhaps you are looking for the download attribute on the <a> tag . Note that it is an HTML5 feature and may not be supported by old browsers and that its behavior can be overridden by Content-disposition header in the HTTP response which the server sends.

If you have control of the server, then adding Content-Disposition: attachment; filename="fname.ext" Content-Disposition: attachment; filename="fname.ext" headers to the response can also lead to the browser prompting the user to download the file.
