Hi,

you was right. before i calculate i check the size of the file. so it works
fine.

in a next step, i like to display the how many seconds will still need until
the copy process is completed.

ich have following information.

1. completly size of all bytes which need to be copy (size)
2. size of already copied bytes (already_copied)
3. percent of already copied size (CGauge2->Progress)

My Idea: Each time, when the timer clocks, i determine the time differenz
from the start of the process to now. and with the bytes which still have to
be copied and the bytes which are already copied, i can calculate the
seconds still needed.

When I start my copy process, i call QueryPerformanceCounter and
QueryPerformanceFrequency before.

QueryPerformanceCounter(&start_ticks);
QueryPerformanceFrequency(&frequenz);
dir_create(ESource->Text,ETarget->Text);

Now I have a Timer in my applcation which clocks echt second.

void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
   rest = size-already_copied;
   QueryPerformanceCounter(&ende_ticks);
   tick_diff = ((double) ende_ticks.QuadPart - (double)
start_ticks.QuadPart)  frequenz.QuadPart;
   if (already_copied > 0)
   LRestdauer->Caption = int(double((double)rest/(double)already_copied) *
(double)tick_diff) + " s";
   Application->ProcessMessages();
}

But my code does not show the still needed seconds, it only shows mysterious
symbols.

Any Idea why this to not works. Is there perhabs a better way to get the
seconds which are need till the process is finished?
