How to download multiple files from s3 on fly?

mamatharao asked in Rails


I am able to download files from s3 as a zip by using below mentioned code.

require 'open-uri'

def download_all_files
folder_path = "#{Rails.root}/public/downloads/"
zipfile_name = "#{Rails.root}/public/"

FileUtils.remove_dir(folder_path) if Dir.exist?(folder_path)
FileUtils.remove_entry(zipfile_name) if File.exist?(zipfile_name)

@model_object.each do |attachment|
open(folder_path + "#{attachment.avatar.file.filename}", 'wb') do |file|
file << open("#{attachment.avatar.url}").read

input_filenames = Dir.entries(folder_path).select {|f| ! f}, Zip::File::CREATE) do |zipfile|
input_filenames.each do |attachment|

send_file(File.join("#{Rails.root}/public/", ''), :type => 'application/zip', :filename => "#{}.zip")


But by using this code, that files are storing in my application. Is there any way to download files directly from s3 or is there a way to remove files which are stored in public folder.

This is a pervasive problem that I still haven't found a solution for.

Select “Standard” if you only plan to upload small amounts of data. Select “Reduced Redundancy” if you plan to upload larger amounts of data. It help me to download document from

Deleting files in a shared folder, if not done correctly. Then you can specify at once to read files from the directory and delete them.
