Please describe the feature

As a [type of user], I want [an action] so that [a benefit/a value].

Detailed description

On Chromium (Chrome / Edge): it is possible to use the File System Access API to write directly into a user-chosen folder, file by file. See here for a description of the API and the first part of option B from here for a sketch of the implementation.

The user can select and download multiple file to their local disk, preserving the directory structure of the file prefixes.
Resuming of downloads is possible.
