This feature is not universally available, but is doc string doesn't
say so (the manual does).
Moreover, setting the variable non-nil unconditionally shows a tooltip
on file names in Dired buffers saying that the user can drag the file
to another program, but that is only so on X; on other platforms it's
a misleading tooltip.
As an aside, changing the value of the variable doesn't affect the
Dired buffers that already exist, only those created afterwards, which
I think is not the best UX.
Can you please fix these issues?
Thanks.

I will work on them ASAP, tho the idea is to have it universally
available by the time Emacs 29 is released. (If nobody volunteers in a
week, I will try to find the time to implement it on NS.)
Thanks.

At least for MS-Windows, I don't think this is a feasible goal, though
I'd be happy to be proven wrong. I think we only support dragging
file names there, and only _into_ Emacs.
So some systems will probably never support this.

I see, too bad. Thanks for explaining.

It shouldn't be too hard, thanks! First, rewrite pgtkselect.c to use
the low-level GDK selections API (the code translates very neatly from
X), since the GTK clipboard API is not very suitable for Emacs
drag-and-drop. The file that needs work is pgtkselect.c.
Then, implement `x-begin-drag' using the GDK drag-and-drop system. I
suggest running a nested event loop until the drop completes.
Most of the low level functions there are not much higher level than the
functions `x_dnd_get_target_window' and `x_set_dnd_targets' on X.
This documentation should be fairly helpful:
