推荐答案
问题在于开发，访问应用程序文件夹不受保护 - 当您安装它时，它是Program Files（或program files（x86））文件夹的一部分，该文件夹受到保护以减少病毒活动。
基本上，不要将任何数据文件放在应用程序文件夹中。
见这里：我应该在哪里存储我的数据？ [ ^ ]它解释了问题，显示了一些很多东西地点，以及如何访问它们。
The problem is that in development, access to the application folder isn't protected - when you install it, it's part of the "Program Files" (or "program files(x86)") folder, which is protected to reduce virus activity.
Basically, don't put any data files in the application folder.
See here: Where should I store my data?[^] it explains the problem, shows some much better places, and how to access them.
