Answer 1

In unit IOUtils.pas you can find the corresponding methods in the records TFile and TDirectory: SetCreationTime, SetLastAccesstime, SetLastWriteTime accompanied by their UTC sibblings.

Answer 2

Try the SysUtils.FileSetDate function from the SysUtils unit, which internally call the SetFileTime WinApi function.

this funcion has two versions

function FileSetDate(const FileName: string; Age: Integer): Integer;
function FileSetDate(Handle: THandle; Age: Integer): Integer;

The Age parameter is the Time to set. You must use the DateTimeToFileDate to convert a TDateTime Value to the Windows OS time stamp.

Like this

FileSetDate(FileName, DateTimeToFileDate(Now));
