Network issue

Greetings!

For years I have been able to copy files to another computer by using a command like this from VFP's Command Window: "copy file my.exe to y:\folder". After I received a Windows Update a few months ago, it no longer works. I get the error "cannot create file". It's not a huge problem because I can use File Explorer to copy/paste the file, but it saves a step.

Just wondering what the Windows Update may have changed? I'm using Windows 10 Home and VFP9.

Thanks.
