从Temp文件夹打开文件时拒绝权限

Question

In my Temp folder, there is one file which is downloaded from browser. I am trying to open this file using Desktop API like this :

File f = new File("C:/DOCUME~1/NJAGAD~1/LOCALS~1/Temp/7870249-0/1234567.pptx");
      try {
        Desktop.getDesktop().open(f);
      } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }

But it gives error like :

java.io.IOException: Failed to open file:/C:/DOCUME~1/NJAGAD~1/LOCALS~1/Temp/7870249-0/1234567. Error message: Access is denied.

If you want to access folders in windows partition you have to change permission. Otherwise you will get this exception.
