Looks great @verasativa ! 🎉 Please see a few minor comments up above.

@verasativa One more thing. Let's add a simple test for this. Take a look at tests/unit/remote/test_remote_dir.py , where we have all of the related code. The test would look something like:

@pytest.mark.parametrize("remote", remotes, indirect=True)
def test_download_dir(remote, tmpdir):
    path = fspath(tmpdir / "data")
    to_info = PathInfo(path)
    remote.download(remote.path_info / "data", to_info)
    assert os.path.isdir(path)
    # check the list of files

The reason why tests are failing 🙂

Suggested change

	from dvc.utils import walk_files

@verasativa Looks great! Just one more minor comment up above and I think we will be done.

Ok, LGTM after @efiop suggestions are resolved

For the record: 1 windows test failed because of temporary issues with chocolatey, that are unrelated to this patch.

Thank you so much! 🎉

For the record: no need to adjust docs, as they already say that we support files and dirs.

EDIT: actually we do need to adjust them, see linked issue below.
