While there is not anything inherently dangerous about zip files on their own, they can often be used for malicious practices, loaded with dangerous content by someone who intends to cause harm to your computer.įor the most part, receiving a zip file from someone you know or that contains files you know would be too large to send through normal email channels is completely normal. We cannot explain zip files without also offering a word of warning regarding the security of using and downloading zip files onto your computer. Of course, there are still benefits to zipping files, such as reduced data usage if your internet is limited, and faster upload if you have a poor internet connection. That said, thanks to cloud-based services that have far higher file size limits than those available from email providers in the 2000s, it’s easier than ever to send and upload your work without having to compress it.

This will allow the service you’re using to easily send the file over the web, without having to worry about your recipient not being able to access the file. So, when should and shouldn’t you zip a file? Typically, if you are trying to send someone a file over the internet, through email or other means, and the file is too large to upload to the server, you will want to make sure you have compressed the file down in size.

Though modern operating systems can view the contents of a zipped folder without having to unzip or decompress the files inside, you typically need to decompress the file before you can use any of the zipped files. zip, which is supported by both macOS and Windows, along with other operating systems such as Android. “Zip” itself refers to the file type of a compressed file.

“Zipping” a file simply means using a utility on your Mac to compress a file or folder down to a much smaller size, without losing any quality in the file or folder. Of course, this can be pretty confusing if you’ve never compressed a file before, so let’s take a look at how it’s done. Zipping your files can compress them down to a much smaller size, saving up to 80 percent of the storage room while maintaining the original quality of the information once the file has been decompressed.Įven better, you can set privacy controls to your zip files, which allows you to control who can see the information and who cannot without having to worry about sending the file over the internet. Zipping, or compressing, a file makes it easy to save some space on your hard drive, and also makes it easy to share those documents and folders with someone through a file sharing service such as Dropbox or Google Drive.

Where older devices might have had 500GB or even a terabyte worth of storage, your new MacBook Pro may only have 256GB in its place. Instead of raising prices, manufacturers like Apple have simple cut storage capacity. Generally, you can expect to pay twice as much for the same amount of storage, though the cost of SSD has been dropping every year. SSDs are clearly the future of computing storage, and it’s not surprising Apple has discontinued traditional or hybrid drives for their computers.īut there is a trade-off to the benefits of SSDs: GB for GB, they’re more expensive than HDDs. From the MacBook Air and 12″ MacBook to the newest generation of MacBook Pros, even up to their iMac and Mac Pro line of desktop computers, Apple has decided that the best choice for storage is SSDs.įlash-based SSDs provide better, faster performance and long lifespans than disk-based hard drives, as well as near-instant computer startups, minimal application launch times, and a slimmer profile. Over the past five years, Apple has switched from using disk-based hard drives to SSDs (solid-state drives) on almost every computer model they sell.
