The GetFileAttributes function returns attributes for a specified file or directory.

DWORD GetFileAttributes(

LPCTSTR lpFileName // address of the name of a file or directory
);
Parameters

lpFileName

Points to a null-terminated string that specifies the name of a file or directory.

Windows NT

There is a default string size limit for paths of MAX_PATH characters. This limit is related to how the GetFileAttributes function parses paths. An application can transcend this limit and send in paths longer than MAX_PATH characters by calling the wide (W) version of GetFileAttributes and prepending "\?" to the path. The "
\?" tells the function to turn off path parsing; it lets paths longer than MAX_PATH be used with GetFileAttributesW. This also works with UNC names. The "\?" is ignored as part of the path. For example, "\?C:myworldprivate" is seen as "C:myworldprivate", and "\?UNCbill_g_1hotstuffcoolapps" is seen as "\
bill_g_1hotstuffcoolapps".

Windows 95

The lpFileName string must not exceed MAX_PATH characters. Windows 95 does not support the "\?" prefix.

Return Value

If the function succeeds, the return value contains the attributes of the specified file or directory.
If the function fails, the return value is 0xFFFFFFFF. To get extended error information, call GetLastError.
The attributes can be one or more of the following values:

Value Meaning
FILE_ATTRIBUTE_ARCHIVE The file or directory is an archive file or directory. Applications use this flag to mark files for backup or removal.
FILE_ATTRIBUTE_COMPRESSED The file or directory is compressed. For a file, this means that all of the data in the file is compressed. For a directory, this means that compression is the default for newly created files and subdirectories.
FILE_ATTRIBUTE_DIRECTORY The "file or directory" is a directory.
FILE_ATTRIBUTE_HIDDEN The file or directory is hidden. It is not included in an ordinary directory listing.
FILE_ATTRIBUTE_NORMAL The file or directory has no other attributes set. This attribute is valid only if used alone.
FILE_ATTRIBUTE_READONLY The file or directory is read-only. Applications can read the file but cannot write to it or delete it. In the case of a directory, applications cannot delete it.
FILE_ATTRIBUTE_SYSTEM The file or directory is part of, or is used exclusively by, the operating system.

The GetFileTime function retrieves the date and time that a file was created, last accessed, and last modified.

BOOL GetFileTime(

HANDLE hFile, // identifies the file
LPFILETIME lpCreationTime, // address of creation time
LPFILETIME lpLastAccessTime, // address of last access time
LPFILETIME lpLastWriteTime // address of last write time
);
Parameters

hFile

Identifies the files for which to get dates and times. The file handle must have been created with GENERIC_READ access to the file.

lpCreationTime

Points to a FILETIME structure to receive the date and time the file was created. This parameter can be NULL if the application does not require this information.


lpLastAccessTime

Points to a FILETIME structure to receive the date and time the file was last accessed. The last access time includes the last time the file was written to, read from, or, in the case of executable files, run. This parameter can be NULL if the application does not require this information.

lpLastWriteTime

Points to a FILETIME structure to receive the date and time the file was last written to. This parameter can be NULL if the application does not require this information.

Return Value

If the function succeeds, the return value is TRUE.
If the function fails, the return value is FALSE. To get extended error information, call GetLastError.

Remarks

The FAT, NTFS, and HPFS file systems all support the file creation, last access, and last write time values.
Windows 95: The precision of the time for a file in a FAT file system is 2 seconds. The time precision for files in other file systems, such as those connected through a network depends on the file system but may also be limited by the remote device.
