How can I get the name of a drive in python
Solution 1
Try the GetVolumeInformation
function instead. It returns the volume label directly.
Solution 2
Why don't you use win32api.GetVolumeInformation?
import win32api
win32api.GetVolumeInformation("C:\\")
outputs
('WINDOWS', 1992293715, 255, 65470719, 'NTFS')
Solution 3
Using the above fragment, I filled in the missing(optional, null) arguments as a quick helper:
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.
Solution 4
You can execute windows shell cmd and parse the output.
in Python 3.x:
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:
import subprocess
def getDriveName(driveletter):
return subprocess.check_output(["cmd","/c vol "+driveletter]).split("\r\n")[0].split(" ").pop()
print getDriveName("d:")
Solution 5
You can below code to get your drive name if you find useful
import win32api
import win32con
import win32file
def get_removable_drives():
drives = [i for i in win32api.GetLogicalDriveStrings().split('\x00') if i]
#print(drives)
rdrives = [d for d in drives if win32file.GetDriveType(d) == win32con.DRIVE_REMOVABLE]
return rdrives
drive_list = get_removable_drives()
for i in drive_list:
print(win32api.GetVolumeInformation(i)[0]+'('+i+')')

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
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)?
EDIT:
Still not working:
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:
WindowsError: exception: access violation reading 0x3A353FA0

Greg Hewgill over 12 yearsThere are three other parameters you haven't passed:
lpVolumeSerialNumber
,lpMaximumComponentLength
, andlpFileSystemFlags
. The "optional" designation in the documentation doesn't mean that you can simply leave them out, but that you can passNULL
as a pointer to that information if you're not interested in the value. -
Eric over 12 years@GregHewgill: Awesome. Thanks!
