Organize your downloads

manageDownload.rb

require 'fileutils'

path = '/Users/rubyginner/Downloads'
docs = ['.pdf', '.epub', '.txt', '.rtf']
pics = ['.png', '.gif', '.jpg', '.jpeg','.bmp', '.JPEG', '.JPG']
music = ['.mp3', '.wav']

archive = ['.zip', '.tar']

Dir.foreach(path) { |dlfile|
  next if ['.', '..'].include? dlfile
  	FileUtils.mv dlfile, path + '/Books' if docs.include? File.extname(dlfile)
  	FileUtils.mv dlfile, path + '/Pics' if pics.include? File.extname(dlfile)
  	FileUtils.mv dlfile, path + '/Music' if music.include? File.extname(dlfile)
  	FileUtils.mv dlfile, path + '/Videos' if videos.include? File.extname(dlfile)
  	FileUtils.mv dlfile, path + '/Apps' if apps.include? File.extname(dlfile)
  	FileUtils.mv dlfile, path + '/Archive' if archive.include? File.extname(dlfile)
}

I haven't tried your script, but I find the following things you might want to try:

• try extension.include? instead of the way you wrote it
• try regular expression matching to get the extension just for practice
• the way you composed your block is good for one liner actions; try using the do block

Anyhow, great work! Very creative! Keep it up!
