Well, not all file names have extensions, so you might want one of these:

( $base, $ext )= $file =~ /^(.*?)([.][^.]*)?$/s;

$ext= ( $base= $file ) =~ s/([.][^.]*)$// ? $1 : "";

$base= substr( $ext= $file, 0,
  0xffff & rindex($file,"."), "" );

/.*?c/s and /[^c]*c/ will always (I'm pretty sure) match the same thing (note the addition of "s" to the first one) as they stand. But you were using these as part of a larger regex, and there they don't always match the same thing. For example, /.*?cd/s and /[^c]*cd/ (adding a "d" to each one) don't always match the same things. On the string "abcabcd", the first will match "abcabcd" while the second will only match "abcd".
