How about `use File::Copy qw(move); my $extension = "12345"; move("file", "file.$extension");` [download] There's also the handy `rename()` function, but is known to have various platform issues. See the `File::Copy` docs for more info. HTH `_________ broquaint`	[reply] [d/l]

my $file = 'file'; my $extension = '.123456'; my $file .= $extension; Update: sorry about that, I misunderstood the question...broquaint's suggestion is the way to go..use File::Copy	[reply]
