Compress and encrypt

Since its launch in 1991, WinZip has become one of the most popular programs for compressing and encrypting files for storage or sending. The latest version builds on the strengths of its predecessors by offering greater capacity, enhanced encryption and compression, and many improvements to the user interface.

To ensure that your files are kept safe from prying eyes, version 9.0 supports 128-bit and 256-bit key AES encryption. To put this into perspective, the US Computer Security Resource Centre Web site estimates that it would take around “149 trillion years to crack a 128-bit AES key”. So, we’d say your files are pretty safe.

To lock down your files, simply choose the encryption strength you want and specify your password. One thing to note is that current recipients of AES-encrypted files must have WinZip 9.0 to decrypt them, although WinZip is working with third parties to expand support for the format.

Now that you know your files will be safe, you might want to store even more, which is fine because WinZip 9.0 has a much higher capacity. The new version’s 64-bit extensions mean you can create archives that hold more than 65,535 files and are larger than 4GB. Despite their enhanced capacity, new Zip files are compatible with the old format.

To ensure that Zip files take up as little hard drive space as possible and are easier to e-mail, version 9.0 uses an ‘enhanced deflate’ compression method that cuts down file size.

Although an upgrade to 9.0 isn’t a must, you will benefit from better security and support for higher capacity. Nervous users might want to wait for the final version that, at time of writing, was not available for download.

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
