Transfering files from client to server VM

Hi,

I have Vsphere running on a client desktop that's manager a few VMs on an ESXi server. I'm trying to transfer files from the client to the server. Currently I'm doing it via USB stick, physically plugging it into the server and adding the USB device to the VM that I'm trying to transfer to. Is there a simpler way that doesn't require me having physical access to the server? Something like shared folders for VM Workstation perhaps?

Thanks.
