Hey monks,

I'm trying to use Archive::Zip to compress some text files for clients to download, but they appear to be corrupted. I get an error message, and only the first file in the .zip is extracted (regardless of which file that is).

I can see all the files when I look at the compressed file contents.

I am using Centos 5.2 x86_64 with perl 5.8.8 and Archive::Zip 1.30. Here is the error message I get: 
warning [/home/student1/Desktop/compounds1310483480.zip]:  104 extra b
+ytes at beginning or within zipfile
  (attempting to process anyway)
file #1:  bad zipfile offset (local header sig):  104
  (attempting to re-compensate)
 bad CRC 50b35a73  (should be 00000000)
file #2:  bad zipfile offset (local header sig):  405
  (attempting to re-compensate)
file #2:  bad zipfile offset (local header sig):  405
file #3:  bad zipfile offset (local header sig):  1020
file #4:  bad zipfile offset (local header sig):  1552

The errors I get when attempting to extract the files in Windows/OSX are 'corrupt/invalid'.

Here is the code I use to create the zip file: 

foreach my $memberName (@MOL2_files)
{
        if (-d $memberName )
        {
        print $log "Adding $memberName\n";
        warn (print $log "Error adding directory $memberName\n")
        if $zip->addTree( $memberName, $memberName) != AZ_OK;
        }
        else
        {
        print $log "Adding $memberName\n";
        $zip->addFile( "/www/mol2/$memberName", "compounds".$time."/".
+$memberName )
        or warn (print $log "Error adding file $memberName\n");
        }
}


open my $fh, ">>", $fullpath or die $!;
print $log "Write Error.\n" if $zip->writeToFileNamed( $fh ) != AZ_OK;

Has anyone seen this problem before and know how to fix it? Or does anyone know of a different module I can use to perform the same function?

Thanks, Tom
