AppCompactor 3.1.0
Shrink the size of portable executable files so they load faster from slow devices

AppCompactor is a powerful tool which enables you to compress portable applications so they require up to 50% less disk space.

Why bother? If you're running an application from slow media, like flash drives or CDs, then you should find they now launch significantly faster. And the programs will decompress themselves automatically, so you don't have to do anything further - just launch your application and use it as you did before.

That's the theory, anyway. This kind of compression won't work with all apps, though, so you should back up your software first. But with that done, AppCompactor is very easy to use: just point the program at your portable installation's folder, choose your preferred compression method (or just select the default), and click Go. In just a moment you'll get a report on how much savings you've made, if any, and you can try the program out to see if you notice any increase in launch speeds.

Please note, malware authors also use this kind of tool to make it harder for security packages to detect them, and as a result antivirus tools may raise an alarm when they detect a compressed executable. AppCompactor is well known, though, so less likely to cause problems than most, but don't be surprised if a packed executable suddenly starts producing virus warnings. It's almost certainly a false alarm (though you should check it at somewhere like VirusTotal, just to get confirmation).


AppCompactor provides a quick and generally reliable way to cut your portable applications down to size. This can cause problems in itself, though, so back up your portable tools before you start, and be aware that a few security tools may complain about the packed executables afterwards.

WhatsApp Messenger 2.12.11

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.

Version 2.12.11 brings:

• Links that you share or receive will now include a rich preview. When sending a link, you have the option to not include a rich preview.
• Additional 3D Touch features: You can now quickly Peek and Pop chats.
• Redesigned Settings tab. 
• You can now view all your starred messages across all your chats in Settings — Starred Messages.
