Firstly I'm describing the situlation:

if current directory (like F:\test\)has some files:

xxx xxx2 xxx3 dst.arc xxxxx xxxxxx ....

and we run such commend:
SomeArc a dst.arc *
or SomeArc a dst.arc F:\test\*
or SomeArc a dst.arc F:\*

As the programmer, how to avoid dst.arc is included in the files to be archived? Or this will obviously cause problem.
