From the File menu, 
choose Save trace to pop up a dialog box to enable 
you to save a trace buffer to a file.  
You enter the filename in a dialog box and 
a file is created for that filename.  
If a file with the specified name already exists, 
you are warned that it will be overwritten.

Choose the directory, enter the file name, 
select the trace mode and fill in the frame range. 
The frame range is for specifying the frame number 
where the trace data will start to be saved, 
and the frame number where will be end.
