Vagrant: Does not sync folder

I'm using:

Windows 10 64bits
Vagrant 1.9.7
VirtualBox 5.1.22
Box Debian Jessie 64bits
Plugins Vagrant:
  >vagrant-vbguest
  >vagrant-share

My Vagrantfile configuration:

Vagrant.configure("2") do |config|
  config.vm.box = "debian/jessie64"

end

I enter the vagrant folder in the virtualized system ( cd /vagrant ), dou ls and it lists Vagrantfile but when I create a folder (in this case I want to use Jekyll, and I use the command: jekyll new my-awesome-site ), the folder is created, and when I give the command ls the system lists the folder along with the Vagrantfile , but the folder does not appear on my system, I give a vagrant reload but it still does not work the folder in my system, and still add after restarting the system).

I have already tested the boxes: ubuntu/trusty64 , hashicorp/precise64 , hashicorp/precise32 . But nothing.

And just after I tried these other boxes I installed the plugins to see if I solved anything, but still nothing.

How can I resolve?

* Remembering that this only occurs when I create a file / folder on the virtualized system (debian in the case), but not the other way around. When I create a folder on windows and start / restart the system, it appears in the /vagrant folder of the virtualized system.
