文件未在/ data / user / 0 / [包名称] / files目录中找到，但可在/ data / data / [包名称] / files目录中找到

Question

我正在从服务器下载zip文件到我的内部存储。它保存到/data/data/[package name]/files目录，我可以使用Android Studio中的设备文件资源管理器查看它。但是当我尝试访问它以解压缩时，我收到以下错误：

java.io.FileNotFoundException: thezip.zip: open failed: ENOENT (No such file or directory)

我打电话的时候：

context.getFileDir();

它给了我以下目录：

/data/user/0/[package name]/files

这是

的符号链接

/data/data/[package name]/files directory

所以我应该可以访问zip文件，不应该吗？

我在这里缺少什么？我希望能够让任何使用该应用程序的用户访问zip文件夹中的文件。救命啊！

编辑：这是代码：

class DownloadFileAsync extends AsyncTask<String, String, String> {
    private Context context;
    private String fileName;

    public DownloadFileAsync(Context context, String fileName){
        this.context = context;
        this.fileName = fileName;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();

    }

    @Override
    protected String doInBackground(String... aurl) {
        downloadZipFile(aurl[0]);
        try {
            unzipFolder(fileName);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;

    }
    protected void onProgressUpdate(String... progress) {
        Log.d("ANDRO_ASYNC",progress[0]);

    }

    @Override
    protected void onPostExecute(String unused) {

    }

    private void downloadZipFile(String link){

            while ((count = input.read(data)) != -1) {

        byte[] buffer = new byte[1024];
        ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream(zippedFile));

            zipEntry = zipInputStream.getNextEntry();
        }

        zipInputStream.closeEntry();
        zipInputStream.close();

    }
