The Best Free Software of 2009..!!part 4

Communication/E-Mail

49. eM Client

Windows
Anyone familiar with Outlook or Thunderbird can master the basics of using eM Client freeware in no time. It already syncs with Google Calendar, and future developments will integrate social networks and IMs with your e-mail.

50. Gmail

Web | Mobile
The current bellwether in Web-based e-mail is still in perennial beta, but Google continues to innovate with additions via the Gmail Labs. The searchable and ever-increasing storage (up to 7GB now, up from 5.5GB last year) doesn't hurt. New themes make it pretty. And you can use it to IM or even send SMS text messages to friends' phones.

51. gAttach
Windows
Usually with webmail, you have to put attachments on a message after the fact. gAttach does it automatically when you select a file, or from within other apps like MS Word, all from the desktop. If you prefer Yahoo Mail,

52. Google Contacts

Windows
This extension for Thunderbird does one thing you need: It synchronizes contacts between Thunderbird and Google's Gmail.
 

53. iContact

Windows
Accessing your Gmail contacts is all the easier with iContact; it displays the normally browser-accessible-only list on your desktop and integrates those contacts into other communications software, like Skype.
 
54. Simple Mail

Windows | Mac OS | Linux
If you already have Firefox open all the time, why not have one of those tabs just for mail? The Simple Mail add-on puts a POP3/IMAP client right inside the browser.
 
55. Thunderbird [HALL OF FAME]

Windows | Mac OS | Linux
The Internet's top e-mail client from Mozilla is (of course) extensible, but even without add-ons Thunderbird is simple-to-master software for anyone with a POP3 or IMAP e-mail account.


56. Windows Live Mail

Windows   
Outlook Express has morphed into the modern-day Live Mail, ready to check POP3, IMAP, and webmail accounts when you're not using it to read RSS feeds or plan your calendar.


57. Yahoo Mail

Web
Our webmail Editors' Choice embeds the Yahoo Messenger IM and RSS reader, works on the Web with any browser or operating system, and has more features than anyone could hope to master.
 
58. Zenbe

Web
Zenbe is a multi-account, Internet-based interface to check Yahoo Mail, Gmail, AOL, Windows Live, and POP3 messages. It throws in a shareable calendar, an address book, and other tools to make it extra-useful. 



File Transfer/Download


63. CrossFTP

Windows | Mac OS | Linux
Built on Java, CrossFTP works and looks the same, no matter which OS you run. It features tabs for each connection, support for archives, and drag-and-drop transfer, and it comes in a free server version, too.

64. DownThemAll
Windows | Mac OS | Linux
Don't download just one item at a time from a Web page. As the name implies, this download manager for Firefox handles them all.

65. Filezilla

Windows | Mac OS | Linux
Slick and simple FTP that does the job, complete with drag-and-drop from local to remote or vice versa.

66. FireFTP

Windows | Mac OS | Linux
Because it's a plug-in for Firefox, FireFTP behaves like any other tab in the browser, so you don't have to launch another application to transfer files.

67. Halite

Windows
Instead of downloading an entire file, apps using the super-popular BitTorrent protocol break files into chunks and distribute them among several users. Free, open-source application Halite is a BitTorrent client focused on using as small of a memory footprint as possible.

68. net2ftp

Web
If you sit at a computer with no FTP software but need to upload a file, stat, this Web app comes to your rescue quickly as long as you have the server, username, and password information.

69. Rightload

Windows
Send a file to preconfigured FTP servers anytime you want with a simple right click. Rightload adds just a single line to the context menu, with fly-out menus for each FTP server you want

70. uTorrent

Windows
Still the best—and smallest—BitTorrent client in existence, uTorrent will have you downloading big files in no time.
