> a.txt
> b.txt
> c.txt
> d.txt

> filea.txt
> fileb.txt
> filec.txt
> filed.txt

> Now I would have thought that this would just be rename files to file*.txt but

> In DOS if I type:

> ren *.txt file*.txt

> I get the same problem. I'm using windows 98 SE and ZTW 1.48kd

> Any ideas on *any* way that I can do this?
