Python judges windows hidden files/system files

In linux, files whose names start with periods (.) are hidden,

Win is determined by the file hiding attribute. Therefore,

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. Hide the property value and its meaning

Constants-the following attribute values are returned by the GetFileAttributes function:

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_normally = 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 uses win32api to obtain the file hiding attribute

Python official website for win32API simple description https://www.python.org/download/windows/

Http://sourceforge.net/projects/pywin32/

= [r filename  %(win32file.GetFileAttributesW(filename), filename)

Running result:

4. more intuitive judgment of hidden files with operations (&)

The sample code is as follows. The calculation result corresponds to the hidden property value, allowing you to more intuitively determine the file type.

= [r filename == file_flag &= file_flag & %(file_flag, is_hiden, is_system, filename)
