I'm looking to save a file (an access token cache) in a place that doesn't get overwritten when my plugin (RingForIndigo) is updated. Seems like the Preferences folder is the right place to do this (i.e. /Library/Application Support/Perceptive Automation/Indigo 7.x/Preferences).
To get this path, is it appropriate to simply append "/Preferences" to indigo.server.getInstallFolderPath()?
