you can access anything in the same folder as the craftbukkit.jar file but i dont believe you can outside of that. should be as easy as defining the file like this: new File("server.properties"). This will tage the location from where the bukkit.jar file is
You can access up to where the CraftBukkit.jar file is in the server. Like so: Code:java File file = new File("plugins" + File.separator + "PLUGIN/FILE here"); Of course to edit/delete it you would need to do some more, but that's how you would get it.
