Open FileSharing | Filemaker Network
With the file selected in the list on the left, click "Don't display in Open Remote Dialog"
The file is being served on a (Local) remote server. Network sharing is set to off, and the "currently open files" box is empty. The open file is called <unknown>
Filemaker Server doesn't give me any options to show or hide the files, and also I mainly want to only restrict the iPhone and iPad users from seeing all of the hosted files, but FM Pro users I'd like them to be able to see the files.
Hope that makes sense!
