I am using CGI to accept an upload from windows machine and write a cab file on my linux server. I then try to use cabextract to open the saved cab file but it says that the uploaded cab file has "2 Extra bytes at end of file". Does anyone have a script to remove extra bytes at end of a file? or does anyone know how to solve this problem? 
#!/usr/bin/perl
#use strict;
use CGI qw/:standard/;
use Digest::MD5 qw(md5 md5_hex md5_base64);
print header();
my $file = param('file');
if (!$file) {
    #file does not exist
     print "Error: No file to upload";
     return;
    }
#Ignore all but cab files
my $fname=$file;
if($fname !~/\.cab$/is){
    print "Error: Not a cab file";
    return;
    }
my $time=time();
my $data='';
while (<$file>) {
     $data .= $_;
    }
my $md5=md5_hex($data);
my $filename="ufiles/$md5\_" . $fname;
if(open(FH,">$filename")){
    binmode(FH);
    print FH $data;
    close(FH);
    #print the MD5 hash as a return value on success
    print $md5;
    }
else{
    print "Failed to upload file";
    }
