If the computer on which the folder you wish to synchronize is located is not a Mac, isn’t running Mac OS X v10.6 or later, or you don’t have administrator privileges on it, you can still synchronize with it using traditional file sharing. (If it is a Mac that you control running Mac OS X v10.6 or later, SynkSharing is a better way to go.)
Setting up the server end of file sharing depends on the details of the server, and is beyond the scope of this document. On a Mac, these settings may be found at Apple Menu () > System Preferences > Sharing. Consult the server’s documentation for full details, or check with the server’s administrator.
After you have the file sharing volume open in the Finder, you can define a folder on that volume in Synk just as you would a folder on your own computer. Just follow the instructions from Defining Locations from Your Mac.
