Flavio, thanks for that!
However, TMemIniFile.Rename cleans up its content with FStream := nil (Am I
correct?). So, In my case I would need to adapt it further so that:
procedure ArchiveIniFileTo(AMemIniFile: TMemIniFile; ADestination : string);
var
TemporaryDestination : string;
begin
TemporaryDestination := AMemIniFile.Filename;
AMemIniFile.RenameAndNothingElse(ADestination);
AMemIniFile.UpdateFile; // Flush data to disc
AMemIniFile.RenameAndNothingElse(TemporaryDestination);
end;
Best,
Rafael Picanço
