i have this file in binmode (its hex bin) and its only 190 or so kb,
the file size varies but that really doesnt matter.
what i am trying to do is open the file in read mode, then find all instances
of FF*16 or (FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF) and delete it,
but only FF*16 because there are other instances of just FF or FF FF and i would like to leave those instances and just delete FF*16. here is the code i have so far: 
open($infile, '<', './file') or die "cannot open file: $!";
binmode $infile;
open($outfile, '>', './modifiedfile') or die "cannot open modifiedfile
+: $!";
binmode $outfile;

local $/; $file = <$infile>;
$file =~ tr/\FF*{16}//d;   
print $outfile $file;


close ($infile);
close ($outfile);

i had some help and figured out that $file =~ s/\0{16}//g; works great for 00's, but it doesnt work for FF's -.-

i hope you understand what i am treing to do, and thank you for any help i recieve :)
EDIT: $file =~ s{\xFF{16}}{}g; worked great.
