獲取磁碟資訊：已使用空間、總空間大小等，python沒有自帶的函式，常用的外掛：WMI

python中自帶的有獲取資料夾大小、名稱等資訊的函式：walk（）

使用wmi之前的配置

環境：

win7、win8
python2.7.7
wmi：1.4.9
pywin32:pywin32-218.win-amd64-py2.7.exe

注意：要下載和自己系統和所安裝python版本相匹配的

因為依賴原因，在安裝wmi之前需要先安裝pywin32；
完成後拷貝解壓後WMI-1.4.9資料夾到安裝python的資料夾裡面（C:/Python27/WMI-1.4.9）
然後在命令列執行：python */Python27/WMI-1.4.9/setup.py install

資料夾大小

    size = 0
            if os.path.exists(dirpath):
                if os.path.isdir(dirpath):
                    for root, dirs, files in os.walk(dirpath):
                        for name in files:
                            try:
                                size += getsize(join(root, name))
                            except:
                                continue
                        #size += sum([getsize(join(root, name)) for name in files])
                elif os.path.isfile(dirpath):
                    size = os.path.getsize(dirpath)
                else:
                    continue
return size

至於#size += sum([getsize(join(root, name)) for name in files])
