使用SQL获取文件夹中的每个文件大小

Question

我们将图像保存在可以有图像和子文件夹的文件夹中,这些子文件夹也可以有图像和子文件夹

c:\myImageFolder\image1.png    //'myImageFolder' have image
c:\myImageFolder\Folder1\imagex.png // 'myImageFolder' have another folder inside which is 'Folder1'.
c:\myImageFolder\Folder1\ChildFolder1\imagen.png // 'myImageFolder' have 'Folder1' which have 'ChildFolder1' which have imagen.png

我们需要知道有多少图像在1 MB以上,超过750KB和500KB？

一些事实:

• 我们需要通过SQL来实现
• 我们正在使用SQL Server 2008
• myImageFolder 包含超过数千个子文件夹
• myImageFolder 大小接近5 GB
