Here is a simple Delphi function that takes a file name as its input, and returns the date and time the file was created. Note that this returns the file creation date and time (creation date/time stamp). This means that if a file is copied from a different drive to a new drive, its creation date/time stamp is reset. Even if a file is copied from one directory (folder) to another directory (folder) on the same drive, the creation date/time stamp is reset.

function GetFileCreationDateTime(FileName: String): TDateTime;
begin
     GetFileCreationDateTime := 0;

     If (FileName <> '') and (FileExists(FileName) = True) then
        begin
             GetFileCreationDateTime := TFile.GetCreationTime(FileName);
             //TFile record is found in the IOUtils unit
        end;
end;
