如何在Windows上访问文件的属性？

Question

上次我问了一个类似的问题，但那是关于svn相关的版本控制信息。现在我想知道如何查询windows的“文件版本”属性，例如dll。我也注意到了wmi和Win32文件模块，但没有成功

以下是一个将所有文件属性作为字典读取的函数：

import win32api

#==============================================================================
def getFileProperties(fname):
#==============================================================================
    """
    Read all properties of the given file return them as a dictionary.
    """
    propNames = ('Comments', 'InternalName', 'ProductName',
        'CompanyName', 'LegalCopyright', 'ProductVersion',
        'FileDescription', 'LegalTrademarks', 'PrivateBuild',
        'FileVersion', 'OriginalFilename', 'SpecialBuild')

    props = {'FixedFileInfo': None, 'StringFileInfo': None, 'FileVersion': None}

    try:
        # backslash as parm returns dictionary of numeric info corresponding to VS_FIXEDFILEINFO struc
        fixedInfo = win32api.GetFileVersionInfo(fname, '\\')
        props['FixedFileInfo'] = fixedInfo
        props['FileVersion'] = "%d.%d.%d.%d" % (fixedInfo['FileVersionMS'] / 65536,
                fixedInfo['FileVersionMS'] % 65536, fixedInfo['FileVersionLS'] / 65536,
                fixedInfo['FileVersionLS'] % 65536)

        # \VarFileInfo\Translation returns list of available (language, codepage)
        # pairs that can be used to retreive string info. We are using only the first pair.
        lang, codepage = win32api.GetFileVersionInfo(fname, '\\VarFileInfo\\Translation')[0]

        # any other must be of the form \StringfileInfo\%04X%04X\parm_name, middle
        # two are language/codepage pair returned from above

        strInfo = {}
        for propName in propNames:
            strInfoPath = u'\\StringFileInfo\\%04X%04X\\%s' % (lang, codepage, propName)
            ## print str_info
            strInfo[propName] = win32api.GetFileVersionInfo(fname, strInfoPath)

        props['StringFileInfo'] = strInfo
    except:
        pass

    return props
