将文件夹从一个本地磁盘移动到另一个

To move folder "aze" to folder "log" and rename it "qsd" in the same local disk, I used :

rename("rename/aze", "D:/log/qsd");

But When I try to move to "C:/test/uploads/qsd" It doesn't work :

rename("rename/aze", "C:/test/uploads/qsd");

My server is in "D" disk.

It looks like it's not possible, so I copy the folder in the destination path and then, delete it in the source path.
