sure does...

But this is not the way to go, you should consider
using some of the build in functions instead of calling the
DOS commands:
findfirst, findnext and mkdir
note that using these functions will make
your program non-portable

You can use the normal C functions, but you should consider using the
file stream objects from C++. I'm not familiar with these functions, and
will give you an example using C syntax.
// In this example we are using a textfile, the functions for

// should be more portable than binary (dont know why).

 SD> Thanks. Steve
We all have to start somewhere, and in my opinion
C_PLUSPLUS is a good place.
