如果Itunes:Keep Itunes Folder Organized是在Windows上以编程方式设置的，我该怎么

Question

如果Itunes:Preferences:Advanced:Keep Itunes Folder Organized是在Windows上以编程方式设置的，我与Itunes交互的Java应用程序需要知道这一点。

不幸的是，iTunes xml文件或iTunes COM API似乎都没有提供这些信息，我认为这是因为它们是存储在其他地方的首选项，但我如何才能知道是否已启用，我还需要知道添加到库时将文件复制到iTunes媒体文件夹

更新：注册表中没有任何内容，但我找到了一个首选项文件

C： \Users\username\AppData\Roaming\Apple Computer\iTunes

不管它看起来是加密/编码的，我不知道如何读取的值

更新2:

保存了文件的副本，在添加到库并进行比较时将"复制文件到iTunes媒体文件夹"的值更改，并获得了更改

但正如你所看到的，很难发现差异，我担心如果我入侵了这个valkue，它可能会在iTunes版本之间中断，有办法解码这个文件吗？

我发现Apache Commons Configuration支持Apples plist格式作为Xml格式http://commons.apache.org/proper/commons-configuration/apidocs/org/apache/commons/configuration/plist/XMLPropertyListConfiguration.html但不幸的是，这里使用的不是二进制格式。

我写了这段代码，列出了所有的密钥，然后尝试解码location属性，因为我知道它只包含一个base64编码器文件路径。

public File getITunesXMLFile()
    {
        String homedir = System.getProperty("user.home");
        File prefsFile = new File(homedir,"AppData/Roaming/Apple Computer/iTunes/iTunesPrefs.xml");
        try
        {
            XMLPropertyListConfiguration xpc = new XMLPropertyListConfiguration(prefsFile);
            xpc.load();
            Iterator<String> keys = xpc.getKeys();
            while(keys.hasNext())
            {
                String nextKey = keys.next();
                System.out.println(nextKey+":"+xpc.getProperty(nextKey).getClass());
            }
            ArrayList location = (ArrayList)xpc.getProperty("User Preferences.iTunes Library XML Location:1");
            System.out.println("Location:"+location.get(0).getClass());
            System.out.println("Location:"+location.get(1).getClass());
            System.out.println("Location1:"+ new BASE64Decoder().decodeBuffer(location.get(0).toString()));
            System.out.println("Location2:"+ new BASE64Decoder().decodeBuffer(location.get(1).toString()));
        }
        catch(Exception ex)
        {
            MainWindow.logger.log(Level.SEVERE,"Unable to open iTunes Prefs file:"+prefsFile.getName(),ex);
        }
        File xmlFile = new File(homedir + "/Music/iTunes/iTunes Music Library.xml");
        if (!xmlFile.exists())
        {
            return null;
        }
        return xmlFile;
    }

但不幸的是，由于数据是作为类型[B的类的ArrayList返回的，这对我来说毫无意义，它不是类的有效名称。

输出为

找到了一个已经支持二进制代码的库.google.com/p/list看起来很有希望

我已经设法使用这个库来解码Xml文件位置，如下所示（Apache Commons Codec 1.8中的Base64类）

public File getITunesXMLFile()
    {
        System.getProperties().list(System.out);
        String homedir = System.getProperty("user.home");
        File prefsFile = new File(homedir,"AppData/Roaming/Apple Computer/iTunes/iTunesPrefs.xml");
        File xmlFile;
        try
        {
            NSDictionary rootDict = (NSDictionary) PropertyListParser.parse(prefsFile);
            NSDictionary userPrefs = (NSDictionary) rootDict.objectForKey("User Preferences");
            if(userPrefs!=null)
            {
                NSData iTunesLocation = (NSData) userPrefs.objectForKey("iTunes Library XML Location:1");
                if(iTunesLocation!=null)
                {
                    String base64 = iTunesLocation.getBase64EncodedData();
                    String filepath = new String(Base64.decodeBase64(base64),"UTF-16LE");
                    xmlFile = new File(filepath);
                    System.out.println(filepath+":File Exists:"+xmlFile.exists());
                    if (xmlFile.exists())
                    {
                        return xmlFile;
                    }
                }
            }
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
            //Use default then
            xmlFile = new File(homedir + "/Music/iTunes/iTunes Music Library.xml");
            if (xmlFile.exists())
            {
                return xmlFile;
            }
        }
        return null;
    }

我试着为我真正感兴趣的数据做这件事，我能够从Documents:132密钥中提取base64编码的数据，但不幸的是，尝试解码这个base64编码并没有真正让我取得任何进展，也许我只需要在启用/禁用标志时寻找base64编码数据的差异。

 public boolean isiTunesCopyFolderToMediaFolder()
    {
        String homedir = System.getProperty("user.home");
        File prefsFile = new File(homedir,"AppData/Roaming/Apple Computer/iTunes/iTunesPrefs.xml");
        try
        {
            NSDictionary rootDict = (NSDictionary) PropertyListParser.parse(prefsFile);
            NSDictionary userPrefs = (NSDictionary) rootDict.objectForKey("User Preferences");
            if(userPrefs!=null)
            {
                NSData options = (NSData) userPrefs.objectForKey("Documents:132");
                if(options!=null)
                {
                    String base64 = options.getBase64EncodedData();
                    System.out.println("optionBase54Data:"+base64);
                    String optionData = new String(Base64.decodeBase64(base64));
                    System.out.println("optionData:"+optionData);
                    return true;
                }
            }
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
        }
        return false;
    }

Answer 1

我复制了打开和关闭设置的iTunesPrefs.xml，然后比较了差异。

检查（真实）

Base64编码：AAIAAAAAAAAAAGAQAA///wEAAHoAAP////8EAEAYAbABAHQAAAAAAAAA

十六进制值：02 01 06 01 017a04 46 6c 61 74

未检查（错误）

Base64编码：AAIAAAAAAAAAAGAQAA///wEAAHsAAP/////8EAEAYAbABAHQAAAAAAAAA

十六进制值：02 01 06 01 017b04 46 6c 61 74

这包含在Preferences:130下，我不知道这些值是如何存储的，也许你可以在上面找到一些东西。考虑使用命令行查找文件中的差异，diff用于linux，fc用于windows。

我知道这不是一个答案，但这不适合发表评论。
