Question:
How can I determine the last access time of a given file?
Answer:
The following example demonstrates retrieving the last date and
time a given file was accessed. Note: Not all file systems support
the last access time.
Example:
procedure TForm1.Button1Click(Sender: TObject);
var
SearchRec : TSearchRec;
Success : integer;
DT : TFileTime;
ST : TSystemTime;
begin
Success := SysUtils.FindFirst('C:\autoexec.bat',
faAnyFile,
SearchRec);
if (Success = 0) and
(( SearchRec.FindData.ftLastAccessTime.dwLowDateTime <> 0)
or ( SearchRec.FindData.ftLastAccessTime.dwHighDateTime <> 0))
then
begin
FileTimeToLocalFileTime(SearchRec.FindData.ftLastAccessTime,DT);
FileTimeToSystemTime(DT,ST);
Memo1.Lines.Clear;
Memo1.Lines.Add('AutoExec.Bat was last accessed at:');
Memo1.Lines.Add('Year := ' + IntToStr(st.wYear));
Memo1.Lines.Add('Month := ' + IntToStr(st.wMonth));
Memo1.Lines.Add('DayOfWeek := ' + IntToStr(st.wDayOfWeek));
Memo1.Lines.Add('Day := ' + IntToStr(st.wDay));
Memo1.Lines.Add('Hour := ' + IntToStr(st.wHour));
Memo1.Lines.Add('Minute := ' + IntToStr(st.wMinute));
Memo1.Lines.Add('Second := ' + IntToStr(st.wSecond));
Memo1.Lines.Add('Milliseconds := ' + IntToStr(st.wMilliseconds));
end;
SysUtils.FindClose(SearchRec);
end;
