Q: Is there a way to default or suggest a folder structure on a direct download without using a zip file?

I have an AngularJS app that I use to generate text files that are imported into a commercial machine. In order for the import to work, the file has to be embedded in a particular folder structure. Is there a way to suggest this folder structure via the download dialog without having to use a zip file?

We use a zip today, but Windows users are having problems with the extracts working on the machine (see this question). Curious if there was a way to bypass the zip altogether.

Relevant info:

Angular version: 5.2.10
Zip Utility in angular: JSZip 3.1.5

JSZip code:

const zip = new JSZip();
zip.folder('FolderA/FolderB/FolderC').file('FILE.TXT', new File([contentString], 'TEMP.TXT', { type: 'text/plain' }));
zip.generateAsync({ type: 'blob' })
  .then(function (content) {
    saveAs(content, 'ZipFile.ZIP');
  });
