如何在Windows上从python获取长文件系统路径

Question

This returns me a short path (DOS convention) (on Windows):

import tempfile
tempDir = tempfile.mkdtemp()
print tempDir

Output >>> c:\users\admini~1\appdata\local\temp\tmpf76unv

Notice the admini~1 .

How can I get/convert this to a full path? eg C:\\users\\administrator\\appdata...

Answer 1

Please try the following code (updated):

from ctypes import create_unicode_buffer, windll
BUFFER_SIZE = 500
buffer = create_unicode_buffer(BUFFER_SIZE)
get_long_path_name = windll.kernel32.GetLongPathNameW
get_long_path_name(unicode(short_path_name), buffer, BUFFER_SIZE)
long_path_name = buffer.value

Hope this helps. Please refer to http://mail.python.org/pipermail/python-win32/2008-January/006642.html

tempDir = win32file.GetLongPathName(tempDir)
