如何在python中获取驱动器的名称 [英] How can I get the name of a drive in python
问题描述
我有一个有效的驱动器号列表,我想向最终用户提供一个选择。我想向他们展示驱动器的名称。这是一些代码,应该向我显示驱动器 F的名称:\
:
I have a list of valid drive letters, and I want to present a choice to the end user. I'd like to show them the names of the drives. Here's some code that should show me the name of drive F:\
:
import ctypes
kernel32 = ctypes.windll.kernel32
buf = ctypes.create_unicode_buffer(1024)
kernel32.GetVolumeNameForVolumeMountPointW(
ctypes.c_wchar_p("F:\\"),
buf,
ctypes.sizeof(buf)
)
print buf.value
但是,此输出 \\?\Volume {a8b6b3df-1a63-11e1-9f6f-0007e9ebdfbf} \
。如何获得Windows在资源管理器中显示的字符串(例如,对于我拥有的某个闪存驱动器,为 KINGSTON
)?
However, this outputs \\?\Volume{a8b6b3df-1a63-11e1-9f6f-0007e9ebdfbf}\
. How can I get the string that windows shows in explorer (eg, KINGSTON
, for a certain flash drive I own)?
仍然无法正常工作:
volumeNameBuffer = ctypes.create_unicode_buffer(1024)
fileSystemNameBuffer = ctypes.create_unicode_buffer(1024)
kernel32.GetVolumeInformationW(
ctypes.c_wchar_p("C:\\"),
volumeNameBuffer,
ctypes.sizeof(volumeNameBuffer),
fileSystemNameBuffer,
ctypes.sizeof(fileSystemNameBuffer)
)
这给了我这个错误:
WindowsError: exception: access violation reading 0x3A353FA0
推荐答案
尝试 GetVolumeInformation
函数代替。它直接返回音量标签。
Try the GetVolumeInformation
function instead. It returns the volume label directly.
