line 24 - remove double " #open my $fileone, '<', "$folder/$file" or die ""$folder/$file": $!";

In case it isn't obvious to anyone reading this, the problem with die ""$folder/$file": $!"; is that there's nothing to say that the second " is a literal character and not simply closing the empty string started by the first " character. Here are some alternatives:

die "'$folder/$file': $!"; # choose a different literal character die "\"$folder/$file\": $!"; # escape the inner " die qq{"$folder/$file": $!}; # use an alternative outer delimiter
