The AppleShare extension enables a Macintosh to access network volumes and services through the Chooser. AppleShare Server software when installed on a Macintosh, allows network users to store, retrieve and share files and applications on a central, dedicated Macintosh server. The extension on an individual Macintosh allows the access the AppleShare Server running on a remote Macintosh.
The AppleShare extension cannot be drag installed because the Installer program must install System resources as well as the extension.
