From : https://bitbucket.org/jankowfsky/winnfsd/issues/13/bug-with-file-creation-on-host

Re-creating an issue that was originally raised here, but looks to be a WinNFSd problem:
winnfsd/vagrant-winnfsd#27
Host OS: Windows 7 Guest OS: CentOS 6.6
Guest is through Vagrant with winnfsd plugin.
Steps to reproduce: 1. Create a file on host file system 2. Do an "ls" from within the VM: the file never appears 3. "touch" the file or otherwise write to it in the VM: the file appears
Same with folders, another way to reproduce: 1. Create a folder on host file system 2. Do an "ls" from within the VM: the folder does not appear, even though you can "cd" to it.
If you need anything to help with this issue, let me know.
