想了解python判断windows隐藏文件的方法的相关内容吗，在本文为您仔细讲解python 判断隐藏文件的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：python,windows,隐藏文件，下面大家一起来学习吧。

1. 通过windows attrib 命令获取文件隐藏属性

Syntax
ATTRIB [ + attribute | - attribute ] [pathname] [/S [/D]]

Key
+ : Turn an attribute ON
- : Clear an attribute OFF

pathname : Drive and/or filename e.g. C:\*.txt
/S : Search the pathname including all subfolders.
/D : Process folders as well

attributes:

        R Read-only (1)
        H Hidden (2)
        A Archive (32)
        S System (4)

   extended attributes:
        E Encrypted
        C Compressed (128:read-only)
        I Not content-indexed
        L Symbolic link/Junction (64:read-only)
        N Normal (0: cannot be used for file selection)
        O Offline
        P Sparse file
        T Temporary

2. 隐藏属性值及其含义
Constants - the following attribute values are returned by the GetFileAttributes function:

复制代码代码如下:

FILE_ATTRIBUTE_READONLY = 1 (0x1)
FILE_ATTRIBUTE_HIDDEN = 2 (0x2)
FILE_ATTRIBUTE_SYSTEM = 4 (0x4)
FILE_ATTRIBUTE_DIRECTORY = 16 (0x10)
FILE_ATTRIBUTE_ARCHIVE = 32 (0x20)
FILE_ATTRIBUTE_NORMAL = 128 (0x80)
FILE_ATTRIBUTE_TEMPORARY = 256 (0x100)
FILE_ATTRIBUTE_SPARSE_FILE = 512 (0x200)
FILE_ATTRIBUTE_REPARSE_POINT = 1024 (0x400)
FILE_ATTRIBUTE_COMPRESSED = 2048 (0x800)
FILE_ATTRIBUTE_OFFLINE = 4096 (0x1000)
FILE_ATTRIBUTE_NOT_CONTENT_INDEXED = 8192 (0x2000)
FILE_ATTRIBUTE_ENCRYPTED = 16384 (0x4000)

For example, a file attribute of 0x120 indicates the Temporary + Archive attributes are set (0x100 + 0x20 = 0x120.)
3. python 通过 win32api 获取文件隐藏属性
python 官网对 win32API 的简单说明 https://www.python.org/download/windows/
下载地址 http://sourceforge.net/projects/pywin32/

复制代码代码如下:

import win32file
·
filenames = [r'D:\test',
             r'D:\test\$RECYCLE.BIN',
             r'D:\test\.file_test.py.swp',
             r'D:\test\file_test.py']

for filename in filenames:
print '%4d, %s' %(win32file.GetFileAttributesW(filename), filename)

运行结果：

4. 与运算（&）更直观判断隐藏文件
示例代码如下，& 运算的结果与隐藏属性值相对应，可以更直观的判断文件类型。

复制代码代码如下:

import win32file
import win32con

filenames = [r'D:\test',
             r'D:\test\$RECYCLE.BIN',
             r'D:\test\.file_test.py.swp',
             r'D:\test\file_test.py']

for filename in filenames:
    file_flag = win32file.GetFileAttributesW(filename)
    is_hiden = file_flag & win32con.FILE_ATTRIBUTE_HIDDEN
    is_system = file_flag & win32con.FILE_ATTRIBUTE_SYSTEM
    print '%4d, %s, %s, %s' %(file_flag, is_hiden, is_system, filename)

运行结果：
