执行自动化脚本时，删除文件夹里旧文件报错。如下
C:\ProgramData\Anaconda2\python.exe F:/AutoStartTime/Record_QQLive.py
删除旧文件 -- 开始
Traceback (most recent call last):

File "C:\ProgramData\Anaconda2\lib\shutil.py", line 268, in rmtree
os.rmdir(path)
WindowsError: [Error 145] : u'QQLive\ad\nocache'

原因： 该文件夹处于被打开状态

解决办法： 关闭文件夹后再执行脚本 。so sad~~~低级错误
