Acronis Files Connect (formerly ExtremeZ-IP) filename policy settings only prevents Macintosh users from adding or renaming files on the server.
Acronis Files Connect filename policy settings are designed to prevent Macintosh users from adding files to the server which do not conform to a policy set by the Administrator. Acronis Files Connect will not modify any existing files on the server (unless the Macintosh user tries to rename a file).
There are a number of utilities available for Windows that will scan an entire drive and rename files. Group Logic has not tested any of these third party applications.
