通过API调用Windows的拷贝文件功能，且在拷贝文件时显示动画及进度。



由于现在的计算机速度都很快，如果源文件不大，可能看不到动画效果!!



你在测试的时候，可以尝试复制一个比较大的文件，效果会比较明显。 -Through the API function call to Windows to copy files, and copy files to display in the animation and progress. As the current speed of the computer very quickly, if the source file is not, may not see the animation!! Your test, they can try to copy a larger file, the effect is more obvious.
