Security rivals thermal paste as the most important thing you have to keep in mind when building or using a system. Every bit of software on your PC should be updated; every external access point into your digital life, closed.  There's no reason why you should be handing over the keys to the castle to random Internet strangers.  Powerful virus protection, a strong firewall, and a bit of common sense -- among other tricks -- will go far to preserve your fortress of a system.

Now that's all well and good for the desktop in your living room, but what about third-party machines?  We've all had to jump on a system over which we've had no control--no observance or administrative rights to ensure that every bit of the operating system checked out to ideal security standards.  You can always head over the falls in a barrel and type your passwords and login credentials blindly, with no foresight or worries that you're inputting valuable information on a potentially infected machine.  That, or you can do what I'd do: Make sure that your every keystroke and action is somehow safeguarded through the use of portable applications that you can carry on a storage device of your choice (cough USB key cough).

And that's exactly what I'll be exploring in this week's Freeware Files: Five awesome portable apps that you can carry with you to increase your security presence on a PC that isn't yours.  These aren't panaceas--you'll still want to be as critical and as cautious as you would previously.  However, they're a step in the right direction toward (hopefully) a data-leak-free lifestyle.

Optical drives aren't potatoes. You can't boil them, mash them, or stick 'em in a stew. And by that, I mean there's simply not that much you can do with your average digital coffee holder. Optical drives read CDs. Optical drives write CDs. And... well, unless you have your drive hooked up to some kind of crazy Rube Goldberg device that feeds your guinea pig whenever you eject the tray, there's simply not much else you're going to be able to do with this essential part of your PC. CD goes in; CD goes out--end of story.

Of course, I'm being a little tongue-in-cheek with this description. There's a great deal you can do with your optical drive on the software side of things. Here's the problem: There are a ton of different programs out there for ripping, burning, and mounting images, amongst other behaviors. Finding the best-in-class application for your device can be like trying to find a tiny scratch on the bottom of the disc itself--a mind-numbing task that's sure to frustrate you as you sift through the 30 different utilities you've pulled down onto your desktop.

Allow me ease the pain a bit. In this week's freeware files, I'll be taking a look at some of the must-have software to supplement your CD drive. With these five apps, you'll be covered for a wide range of uses--ripping all different kinds of media to your (presumably) terabytes of storage space, burning your own custom discs and presentations based on preexisting files, and converting physical media to digital images that you can pull up off of your hard drive instead of ever having to fiddle with a disc again.

Grab a CD-R coaster for your drink and join me after the jump for all the software goodies!

It's difficult to envision a life without email. I'm not sure if that's a good or a bad thing. Suffice, digital messaging is just a fact of geek life that we all have to deal with on a daily basis. Whether your inbox gets flooded with messages like the Nile during rainy season, or it's barren as one of those outback wastelands that Bear Grylls likes to visit, you probably aren't using your email client of choice to its fullest potential.

That's ok. Neither was I before undertaking the research for this week's open-source and freeware roundup. But now that I have seen the light, as it were, I would never go back to the ol' vanilla installations of Outlook, Thunderbird, Gmail, or whatever one's particular email utility of choice happens to be.  There are just too many interesting ways to tweak and alter the normal email experience to better enhance your ability to read, organize, and shuffle your messages.

That's kind of "the big point" of the roundup this week--making your email work better for you. Click the jump, and I'll show you five apps and utilities for taking your email processing to the next level!
