[Feature Request] Hope Emacs can provide an async version of `url-copy-file'

[Feature Request] Hope Emacs can provide an async version of `url-copy-file'

[stardiviner]

Because sometimes network is not good, so downloading might suspend Emacs for a
long time. So I'm trying to implement an async downloading of `org-attach-url'
in org-mode. But it require async version of `url-copy-file', write redundant
code is not useful. Also I'm not able to implement that. So I send email for
feature request here.

Thanks in advance.

Would using threads work for your use case given that it's network
I/O. For example, this downloads a large file without blocking Emacs:

#+begin_src emacs-lisp
(make-thread (lambda () (url-copy-file "https://speed.hetzner.de/100MB.bin" "/tmp/test.txt")))
#+end_src

Best,

Thanks Narendra, this indeed is an great simple solution.
