Hello Monks! I am a new Perl programmer and using command prompt to compile in Windows enviornment. Please see my code below and help understand why its not working. I am trying to get all the file names in a folder into an array and then compare it to all the file names in a .txt file. The names in the array that are not in the file is stored in a different .txt file and also added to the original .txt file. Everything till the second comment works fine. Please excuse me if the code structure is not optimal... still learning the ropes. Thank you! 
##########################
my $directory = 'C:\';

opendir(DIR, $directory);
my @files = grep { $_ ne '.' && $_ ne '..' } readdir DIR;
closedir(DIR);

# storing all file names in the folder in an array

foreach(@files){
    print $_,"\n";
}

# emailsent.txt-will contain the name of all files for whom an alert h
+as been sent
# emailtogo.txt-will contain the name of all new files for whom an ale
+rt has to be sent


my $matchfile = 'emailsent.txt';
my $outfile = 'emailtogo.txt';

open (IN, ">>$matchfile");
open (OUT, ">>&outfile");

# Comparing the array to the names in $matchfile

foreach(my $file = @files){
    for my $file2(<IN>){
    if ($file ne $file2){
    print OUT $file;}
    }

#Insert names to original text file

my @files = <OUT>;

foreach(@files){
    print IN, "\n";
}

close(IN);
close(OUT);
