this is the final revised working code:

use File::Path qw(make_path);

open (my $infile, '<', 'file') or die "cannot open file: $!";
binmode ($infile);
make_path ('./extracted');

my $curpos = '';
my $fileLocation = '';
my $fileSize = '';
my $fileName = '';
my $file ='';
my $chunk = '';
my $empty = '';

#GET File Location, File Size, File Name and write to file
seek ($infile, 0x10, 0);
until ($curpos =~ 0x04c0){
$curpos = tell $infile; 
    seek ($infile, $curpos, 0);
    read ($infile, $fileLocation, 0x08);
$curpos = tell $infile;
    seek ($infile, $curpos, 0);
    read ($infile, $fileSize, 0x08);
$curpos = tell $infile;
    seek ($infile, $curpos, 0);
    read ($infile, $fileName, 0x20);
$curpos = tell $infile;
        
        $fileLocation =~ s/(.)/sprintf("%02x",ord($1))/eg;
        $fileSize =~ s/(.)/sprintf("%02x",ord($1))/eg;
        $fileName =~ s/\0+$//;
  
 open($file, '>', "extracted/$fileName") or die "Cannot open $fileName
+ $!";
    binmode($file);
    sysseek ($infile, hex($fileLocation), 0);
    sysread ($infile, $chunk, hex($fileSize));
    syswrite ($file, $chunk);
            
$fileLocation = '';
$fileSize = '';            
};
