Hi guys,
I remember that we used to use DWSDownload.aspx with a File parameter for forcing the download of files.
Is this still usable in DW10 or there is another alternative?

Thank you,
Adrian

Hi Adrian,

DWSDownload.aspx no longer exists in DW10.

What can be used instead:

For image files — the Image Handler supports ForceDownload=true as a query parameter, optionally combined with FileName=customname.ext:

/path/to/image.jpg?ForceDownload=true&FileName=my-download.jpg

For non-image files (PDFs, docs, etc.) — there is no built-in URL-based equivalent. Your options are:

  1. HTML download attribute (client-side, same-origin only):

    <a href="/Files/Files/example.pdf" download="example.pdf">Download PDF</a>

  2. Custom middleware/controller endpoint that reads the file and writes the attachment headers manually.

The download attribute covers the most common template use case.

BR, Dmitrij
