How to make a ZIP file on a Mac

How to make a ZIP file on a Mac 

you may want to know how to use these files to transmit data, whether for work or personal use. Here is how to make a ZIP file on a Mac.

So, what is a ZIP file?

When you need to send lots of data, you might be distraught at how long it takes. This can be especially troublesome with music or video files, which, depending on the format, could take hours to upload or download. The way around this is to compress the files, either by eliminating redundancies in the files, which can then by recreated (lossless compression) or by cutting out unnecessary bits, albeit at the cost of a perfect replica (lossy). Compressed files are packed into various archive formats such as RAR and ZIP. When you download a compressed file, you will need to extract the contents — or “unzip” them — in order to access them.

How to create a ZIP file on a Mac

Creating a ZIP file on a Mac is quick and easy, as MacOS contains a built-in utility for compressing or unzipping files.
First, find a file or group of files you want to compress. For a single file, simply right-click it and select Compress [file name].

You will see a ZIP file appear in the same folder as the original, which will still be present.

How to unzip a file

Unzipping a ZIP file is about as easy as creating one. Simply right-click the file in question, hover over Open With, and choose Archive Utility (or a third-party unzipping program, if you have one).

MacOS will automatically create a new folder containing the zipped files in the same location as the ZIP file. If you want to secure your ZIP files with a password, we have a guide for that, too.

How to encrypt and password-protect ZIP files the right way


 An anonymous reader asked “Is there any way to crack a password-protected zip file?”

That question can be interpreted two ways. Do you want to hack into someone else’s private files? Or do you want to avoid a form of encryption that won’t give you much protection? Since I believe that most PCWorld readers are inherently good people, I’ll assume that you simply want to be assured that your files will not be cracked.

For some years now, the .zip format—intended primarily for compression—has provided encryption as an added feature. But what kind of encryption it provides depends on the program you use to create and open the ZIP file.

The .zip format supports two forms of encryption and password protection. The first, nicknamed ZipCrypto, is relatively easy to crack. I’m not saying that anyone could do it, but the Info-ZIP organization calls ZipCrypto ”quite weak”—a view shared by other organzations as well.

You’d be far safer using the other option, AES-256. Unlike ZipCrypto, AES was not designed for ZIP files. It’s a popular and extremely strong encryption technique used in many programs. Assuming you use a strong password, it’s for all practical purposes unbreakable.
But when you use it for ZIP archives, AES-256 comes with another problem: Windows’ own, built-in compression tool doesn’t support AES. Email someone an AES-encrypted file, text them the password (safer than emailing it), and if they try to open it in Windows Explorer or File Explorer, they won’t be able to open any of the files within the archive.
Fortunately, most third-party zip tools, including the free 7-zip, support AES-256. To encrypt an archive in 7-zip, once you’re at the Add to Archive dialog box, enter a password and select the Encryption method AES-256. You’ll find these options near the lower-right corner of the dialog box.
One more problem with encrypted ZIP files: No matter which form of encryption you use, anyone with access to the files can see the name of the files within the archive. If the file names provide sensitive information, a thief could take advantage of that. Of course, they would not be able to open any of the files without the password.

HOW TO PASSWORD A PDF FILE

A reader asks:
“Is there any way to password-protect and lock a sensitive PDF file before sending it as an attachment through email? I cannot afford Adobe Acrobat Pro and free primopdf didn’t work for me. Any help will be appreciated!”
The quickest way to do this is to ZIP the PDF file and protect the ZIP file, or use Microsoft Office’s built-in encryption tools to create a password. If you use Outlook, you can use Adobe Acrobat IX to password protect PDFs. You can also try programs like NitroPDFand PDF Encrypt to set the password protection to your PDF file without Acrobat.

Guardians of the Galaxy game UK release date and gameplay rumours, plus trailer

Guardians of the Galaxy game UK release date and gameplay rumours, plus trailer

Here's everything we know about Telltale's episodic game of Marvel's Guardians of the Galaxy

Guardians of the Galaxy is Marvel's first game in partnership with Telltale Games, who've already made games based on The Walking Dead, Batman, and Game of Thrones. Here, we discuss the potential release date for the five Guardians of the Galaxy episodes, along with what to expect in terms of gameplay and storyline.

Guardians of the Galaxy game UK release date rumours: When is Guardians of the Galaxy episode one coming out in the UK?

Guardians of the Galaxy game UK release date: 2017

All we know for sure about the release of the first episode of Telltale's Guardians of the Galaxy game is that it's due some time in 2017. Telltale confirmed the 2017 release date in a blog post shortly after revealing the game at The Game Awards 2016, writing that the five-part episodic series will "premiere digitally in 2017."
We can speculate about a more precise release date though. Guardians of the Galaxy Vol. 2, the upcoming sequel to the first film, hits UK cinemas on Friday 28 April 2017, and it's a pretty reasonable guess that Marvel and Telltale will be timing the release of the game's first episode to capitalise on the excitement around the film's release. That means we can likely expect Guardians of the Galaxy Episode One to release some time in April 2017, with the remaining four episodes over the following few months. 
As for release platforms, the game will apparently come out on "home consoles, PC, and mobile devices." That means we can expect it on the PlayStation 4 and Xbox One, along with Android and iOS, and maybe even the Nintendo Switch.

We’ll update this section with more information as soon as it becomes available.

Guardians of the Galaxy gameplay rumours: What can we expect from the Guardians of the Galaxy game?


We don't know much about the game yet beyond its official title: Marvel’s Guardians of the Galaxy: The Telltale Series. 
Telltale released a first teaser video for the game (shown above), but it doesn't reveal much except that fans can expect the same sort of tongue-in-cheek soundtrack choices that helped make the Marvel film so popular. Thankfully, Telltale co-founder and CEO Kevin Bruner has revealed a little more about what to expect in the official blog post.
"The energizing blend of humor, emotion, teamwork, and full-on sci-fi action-adventure of the Guardians provides an enormously satisfying space to explore through Telltale’s unique style of interactive storytelling. In Marvel’s Guardians of the Galaxy: The Telltale Series, players will take on multiple roles within the ragtag band of heroes, and take the pilot’s seat in directing their escapades around the universe. We are always honored to be working with the best creative partners and storytellers in entertainment, and working with Marvel on this series leaves us excited to share what we’ve been developing when it premieres in 2017."

That sounds about like what we'd expect from one of Telltale's games, which have popularised episodic interactive storytelling. Going by previous Telltale titles like The Walking Dead and Batman, we can expect some branching narrative options and hefty moral choices, with more of an emphasis on interacting with other characters than on big action-packed set pieces. 

There's no word yet on whether the Guardians of the Galaxy game will be the first to sit within the official continuity of the Marvel Cinematic Universe, or on whether we can expect cast members like Christ Pratt, Zoe Saldana, and Bradley Cooper to reprise their roles from the film. 
This is expected to be the first of several Marvel games that Telltale is working on, but neither company has revealed what other titles they might be working on. We'll update this as we know more about the Guardians of the Galaxy game and any of the other projects.

How to make sure all your PC components are compatible

How to make sure all your PC components are compatible

There's nothing worse than ordering a bunch of PC parts online, receiving the delivery and finding out that the CPU you've ordered isn't compatible with the motherboard. Some components like the CPU, have specific characteristics that only work with supported hardware. You won't be able to install an Intel CPU into an AMD socket motherboard, for example. We take a look at some ways you can help avoid this.


The main culprit when it comes to compatibility issues is the motherboard, which has to work with various other components, like the CPU, RAM, and more. It's the heart of the PC and needs to interact with various connected hardware, and thus we need to be vigilant when checking specifications and requirements. Here are a few tips that will help to ensure the motherboard and other parts you're purchasing will work together:
  • Check the motherboard CPU socket and compare against your chosen processor.
  • See what RAM the motherboard supports (example being DDR4 2300MHz).
  • Similarly to the board, see what RAM the CPU can support.
  • Whether or not the motherboard will support an GPU SLI configuration.
  • Check ATX size and dimensions when fitting inside smaller cases.
  • Ensure your PSU will provide enough juice.

PCPartPicker 


There's a handy website that can help out with configuring a new PC build (or an upgrade if you select what hardware you have already installed. Working with the CPU first, the system actually eliminates incompatible motherboard sockets and RAM. Should you somehow manage to add in various items that simply won't work together, the website will throw out an alert for you to fix an issue.
There are some handy little features as well, like the ability to save and share builds. Should you be new to system building, this makes it possible for you to have your list of components checked over by someone with more experience who can verify the build and possibly recommend cheaper alternatives to save a little cash. As an added bonus, it will even provide a rough estimate as to how much power the PSU will need to output.
Overall, PCPartPicker is a invaluable tool when it comes to picking out parts for a new PC.

Does the power supply inside your PC provide enough juice?

Does the power supply inside your PC provide enough juice?

If there's one component you simply cannot cheap out on, it's the power supply (PSU). We run through how you'll be able to tell what you'll need.
When looking at various build plans or a new components to upgrade, one has to consider the power supply unit. Can it provide enough power? Is it from a reliable brand to ensure a stable supply? These are but just two questions that will need to be answered and thankfully we can lend a helping hand, not to mention there are handy calculator tools available that can determine whether or not you require additional power.
The power supply unit needs to provide enough stable electricity to the motherboard, CPU, GPU, connected hard drives, any case mods and fans. While manufacturers offer up TDP calculations and the like, it remains fairly difficult to accurately calculate exactly how much power you're going to need.
There's a safe margin that's considered more than adequate for a single-GPU PC build: 500W. You'll be able to power not only the GPU, which requires separate power connections as you hit the more demanding segments, but also numerous fans, some lighting and everything else in-between. The goal is to not go with the highest watt, but the best in the business for your buck.
It's better to go for a reliable model from a reputable brand that has just 500W-750W capacity over a more affordable 1500W PSU. Often the marketed capacity is what the unit will be able to provide at peak under full load. Your PC not only requires power, but "clean" and stable power. It's all about frequencies, how much juice is provided through the 12v rails, whether you have modular cables to keep everything tidy and improve airflow, silent operation, and higher efficiency.

Calculate your needs

There are a number of calculation tools available that help give you an idea as to what capacity you should be looking at. While we'd not recommend you need anything more than 500W or 750W at the most, if you're looking to throw in a second GPU, or simply wish to future proof for upgrades, you may need some more capacity. Find below a list of tools that can be used to estimate how much power your system may draw:
While we urge folk to give these tools a try if you're not entirely sure what you'll need, they shouldn't be used as final verdicts. After calculating your PC build, see our best power supply round-up and work from there.

Microsoft's virtual reality headsets will run even on modest PCs

At an event to announce its feature-packed Creators Updatefor Windows 10, Microsoftrevealed that it's working with hardware makers to release PC-tethered VR headsets that'll start at $299 - a lot cheaper than existing options like the Oculus Rift and HTC Vive.
The trouble with the current generation of headsets is that they not only cost a lot on their own, but also require high-end PCs to VR experiences on them - raising the price of admission to at least $1,500. The Verge reports that Microsoft's cheaper offerings won't be all that demanding.
It noted that a "Windows Holographic First Run" app for testing compatibility with Microsoft's upcoming VR platform is included in the latest test builds of Windows 10, and it revealed the minimum hardware requirements for VR experiences:
  • 4GB of RAM
  • USB 3.0 port
  • A graphics card with DirectX 12 support
  • 4 CPU cores, including dual-core processors with hyperthreading
That's not scary at all, and it should be possible for most folks with modest PCs to give VR a try. Of course, we'll have to wait and see what sort of apps run on such machines.
Plus, Alex Kipman, who heads the HoloLens project at Microsoft, said that the upcoming range of VR headsets will offer different classes of experiences across numerous price points. He explained, "There is a difference if you want to play Halo or you want to play Solitaire. The entry to play anything was a $1,500 PC; that's what we lowered."
Microsoft is also expected to share more information about how the headsets will work next month, when it hosts a couple of Windows Hardware Engineering Community (WinHEC) events - the first will be in Shenzen, China, on December 8-9; the second will be in Taipei, Taiwan from December 14-15.
