python判断windows隐藏文件的方法

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 

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)

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)

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。

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：
