Adobe Digital Editions 3.0

Ever wondered how you can open eBooks with the format epub, aeh, irx etc. Well there are plenty of softwares in the market, but I am guessing that you will not get the feel of reading it as a book, but more like a pdf document. Well Adobe has found a solution for you. The software devlopment company which makes you pay for every software you download, finally releases a software where you don't have to actually pay for anything.

Tixati

Torrents are not even required of mentioning. But still I will write about it for rookies. Torrents are a very complicated version of your home peer-to-peer system. I won't get into the working of torrents but I'll tell you how to download one. To download a torrent you will need a bit-torrent client. Here I will be mentioning a very unfamiliar client. It's name is Tixati. 

I know most of you are using the very familiar "utorrent", but I would suggest you to use Tixati as it is faster and very light. Although the appearance maybe be rather unwelcome, you will get used to it.

Sorry Mac users, Tixati is only available for Windows and Linux.

Tixati can be downloaded from here.

7-Zip

7-Zip has quickly become the de facto leader when it comes to getting a free tool to pack and unpack compressed archives. It supports packing 7z, TAR, ZIP and other formats, and about four times as many for decompression. Throw in some AES-256 encryption and it's a great security tool, too. This software comfortably works on both Mac and Windows
