mmh not sure if i have understood all your question.. anyway i have some hints for you.

First your method to get the file list ($i = 6000000) is, mmh how to say, bizarre? Perl has a glob function, use it.
Second, never use bareword filehandles (FH) use the lexical form.

Third if you really have so much files then copy a little bounch of them (with some positive case included) in a development directory and write your script against them, so you'll have a fast feedback.

A basic approch can be similar to this pseudo-code 
#pseudo-code

$|++; #flush output to stdout as soon as possible
my @files = glob '*.txt';

foreach my $file (@files){
  my ($var_one, $var_two ...); #your var names to be checked
  open my $fh, '<', $file or die "...";
  while (<$fh>) {
     #use regex to put something inside  $var_one, $var_two
  }
  #
  if (all vars needed are defined and pass your check){  print  "$file
+ IS VALID\n"; system 'mv $file  /new/path'  }

}
