Hi, Thank you for the response. I tried to read file using Archive::Zip code looks like -- #!/usr/bin/perl use warnings; use strict; use Archive::Zip qw( :ERROR_CODES ); # Read a Zip file my $somezip = Archive::Zip->new(); my $fname = $ARGV[0]; unless ( $somezip->read( "$fname" ) == AZ_OK ) { die 'read error'; -------------------------------- The code is throwing en error which says- 'format error: Can't find EOCD signature' File is a .gz file. Do you have an idea what this error is about? Thank you.
