It's customary to mark updates to your post, take a look at How do I post a question effectively?/PerlMonks for the Absolute Beginner. If you look at the documentation for Net::FTP the get method states "Get REMOTE_FILE from the server and store locally...". Your question was "I have been trying to create zip file of a folder containing some files on FTP server from client machine.", but your code shows logging into a server and retrieving a file. If you are trying to create a zip file of a directory on the FTP server, you won't be able to use FTP to do this. If you want to retrieve a directory from a server and create a zip file you can use Net::FTP to transfer the files then create a zip file. If you just want to create a zip file on the FTP server see my previous reply.
