If you want to share between Windows machines and Macs go to your Mac's System Preferences application and the Network settings and click this button to turn on Window's sharing. Then your PC should be able to see the Mac as part of a Windows network.<br><br><br><br><br><br>Personally, (for whatever reason) I've had mixed results with that. So, another option is to turn on FTP access (its already on in the example picture above). Then your mac becomes an FTP server and can be connected to with any FTP client. If you don't know what that is, check the help files, or write back here and someone can step you through it. These are good things to know.<br><br>
