如何在cmd下显示硬盘容量更直观

[habulu]

如题，要显示硬盘已用容量和剩余容量，最好还要个已使用容量所占百分比，这个命令可以显示：
WMIC LOGICALDISK WHERE MEDIATYPE='12' GET DESCRIPTION,DEVICEID,FILESYSTEM,SIZE,FREESPACE

Description DeviceID FileSystem FreeSpace Size
Local Fixed Disk C: NTFS 67822944256 107376275456
Local Fixed Disk D: NTFS 175455567872 215458754560
Local Fixed Disk E: NTFS 153090928640 177163763712

上面是用比特为单位的，能用G为单位显示吗，最好再再来个FreeSpace / Size 的比值
求高手指教

这个命令我的WIN7没效果, 那就需要写一个小程序了,把这些文本内容解析后,转成G单位重新显示. 语法稍作修改如下: WMIC LOGICALDISK WHERE MEDIATYPE='12' GET DESCRIPTION,DEVICEID,FILESYSTEM,SIZE,FREESPACE | MyProg.exe

命令行窗口下本来很多东西就很不直观，干吗非得要在命令行窗口下去看？非得要这样的话建议写PowerShell或VBS脚本来实现。
