Question about custom.xml

[s5n4K3s]

Hi there!
i see a custom.xml file

Code: Select all

         File[] files = dir.listFiles();        for (File f : files)        {            if (f.getName().endsWith(".xml") && !f.getName().startsWith("custom"))                hash.add(f);        }        File customfile = new File(Config.DATAPACK_ROOT, dirname + "/custom.xml");        if (customfile.exists())            hash.add(customfile);    } 

in gameserver/skills/SkillsEngine.java

What can i do with this file? can i overwrite existing skills and create new ones?
Thanks!
