How can I get the name of a drive in python
提问by Eric
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:\:
我有一个有效驱动器号的列表，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。这是一些应该向我显示驱动器名称的代码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
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)?
但是，这输出\\?\Volume{a8b6b3df-1a63-11e1-9f6f-0007e9ebdfbf}\. 如何获取 Windows 在资源管理器中显示的字符串（例如KINGSTON，对于我拥有的某个闪存驱动器）？
EDIT:
编辑：
Still not working:
还是行不通：
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)
)
This gives me this error:
这给了我这个错误：
WindowsError: exception: access violation reading 0x3A353FA0

Try the GetVolumeInformationfunction instead. It returns the volume label directly.
试试这个GetVolumeInformation功能吧。它直接返回卷标。
回答by Felix Heide
Why don't you use win32api.GetVolumeInformation?
为什么不使用 win32api.GetVolumeInformation？
import win32api
win32api.GetVolumeInformation("C:\")
outputs
输出
('WINDOWS', 1992293715, 255, 65470719, 'NTFS')

Using the above fragment, I filled in the missing(optional, null) arguments as a quick helper:
使用上面的片段，我填写了缺少的（可选的，空的）参数作为快速助手：
import ctypes
kernel32 = ctypes.windll.kernel32
volumeNameBuffer = ctypes.create_unicode_buffer(1024)
fileSystemNameBuffer = ctypes.create_unicode_buffer(1024)
serial_number = None
max_component_length = None
file_system_flags = None
rc = kernel32.GetVolumeInformationW(
ctypes.c_wchar_p("F:\"),
volumeNameBuffer,
ctypes.sizeof(volumeNameBuffer),
serial_number,
max_component_length,
file_system_flags,
fileSystemNameBuffer,
ctypes.sizeof(fileSystemNameBuffer)
)
print volumeNameBuffer.value
print fileSystemNameBuffer.value
This should be copy-and-paste-able.
这应该是可复制和粘贴的。

You can execute windows shell cmd and parse the output.
您可以执行 windows shell cmd 并解析输出。
in Python 3.x:
在 Python 3.x 中：
import subprocess
def getDriveName(driveletter):
return subprocess.check_output(["cmd","/c vol "+driveletter]).decode().split("\r\n")[0].split(" ").pop()
print (getDriveName("d:"))
in Python 2.7:
在 Python 2.7 中：
import subprocess
def getDriveName(driveletter):
return subprocess.check_output(["cmd","/c vol "+driveletter]).split("\r\n")[0].split(" ").pop()
print getDriveName("d:")

- returns driveLetter for the given driveLabel
- returns "notfound" if driveLabel was not found
- 返回给定 driveLabel 的 driveLetter
- 如果未找到 driveLabel，则返回“notfound”
def findDriveByDriveLabel(driveLabel):
def findDriveByDriveLabel(driveLabel):
drvArr = ['c:', 'd:', 'e:', 'f:', 'g:', 'h:', 'i:', 'j:', 'k:', 'l:']
for dl in drvArr:
try:
if (os.path.isdir(dl) != 0):
val = subprocess.check_output(["cmd", "/c vol " + dl])
if (driveLabel in str(val)):
return dl + "/"
except:
print("Error: findDriveByDriveLabel(): exception")
return "notfound"
