SetFileTime

The SetFileTime function sets the date and time that a file was created, last accessed, or last modified.

BOOL SetFileTime(

HANDLE hFile,	// identifies the file
CONST FILETIME *lpCreationTime,	// time the file was created
CONST FILETIME *lpLastAccessTime,	// time the file was last accessed
CONST FILETIME *lpLastWriteTime	// time the file was last written
);

Parameters

hFile

Identifies the file for which to set the dates and times. The file handle must have been created with GENERIC_WRITE access to the file.

lpCreationTime

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

lpLastAccessTime

Points to a FILETIME structure that contains 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 need to set this information.

lpLastWriteTime

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

Return Values

If the function succeeds, the return value is nonzero.

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

Remarks

The FAT and New Technology file systems support the file creation, last access, and last write time values.
