Yes. File sharing can be disabled in two ways:
* By not enabling the sharing functionality with the Sharing Setup control
panel (the button next to File Sharing should say "Start").
* By not installing the file sharing software. Either choose the Custom
option in the system software Installer program, or simply drag the File
Sharing extension out of the Extensions folder in the System Folder.
Here are the steps for turning off File sharing:
1) Open your Control Panel folder.
2) Open Sharing Setup Control Panel.
3) Click the "Stop" button for file sharing. The button name should change
to "Start".
