O&O Defrag v20
Ramp up your PC's performance with this very configurable defrag tool

O&O Defrag is a powerful and highly configurable hard drive defragmentation package.

At first the program looks much like any other defrag tool. Launch it, and you'll be presented with a list of your drives. Selecting one displays the usual mosaic-style map of its file layout. Then click Start and just watch as O&O Defrag reorganises its files to deliver the maximum possible performance.

This is just the start, though. Do you have multiple drives, for example? Select as many as you like and the program can defragment them all, simultaneously.

You don't have to use one particular defrag strategy, either. Instead you can have your files organised by their file name, access date, last modified date and more, whatever best suits your needs. Or if that's not enough then you can set up an entirely custom layout scheme which optimises Windows, application files and your user data to deliver the best possible system performance.

As you might guess, this probably isn't the best choice for the PC novice. But it's not overly complex, either. Once you've set O&O Defrag to work as you'd like, it'll run mostly in the background, defragmenting your hard drive automatically as required, while you get on with other things. And because it's so light on resources, and can be configured not to run at all if your system is busy or other heavy-duty programs are running, it's most unlikely to ever get in your way.

What's new in v20.0?

- New: O&O DiskStat integrated! O&O DiskStat provides you with an overall view of just how your hard disk is being used.
- New Design: For version 20 we have gifted O&O Defrag a brand new design
- New GUI: We have revamped the entire GUI structure to make using O&O Defrag even easier and quicker for you


O&O Defrag is a powerful and very configurable defrag tool, that will not only correct existing fragmentation problems, but also automatically optimise your hard drive in real time to prevent them from reoccurring in the future

The official retail price for O&O Defrag version 17 is actually $29.95 and not $19.99 as shown in this article currently. That may have been an older price for a previous version. reply:

Hi Marc, the $19.99 price referred to in the article is the price we're selling Defrag 17 from the Downloadcrew Software Store. See for more info.

WhatsApp Messenger 2.16.11

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's new in 2.16.11?

 - Due to a bug in iOS 10, your notification sounds may not properly play until you restart your iPhone (press and hold the power and home buttons for 10 seconds).
- In groups, you can now mention specific people to get their attention by typing the @ symbol and choosing someone from the picker. 
- When forwarding messages, you can now send to multiple chats at once 
- Ask Siri to send WhatsApp messages or place WhatsApp calls (iOS 10+) 
- Answer WhatsApp calls right from your lock screen, just like a standard phone call (iOS 10+) 
- A new Widget lets you quickly jump to a recent chat or see which chats have unread messages (iOS 10+)
