ZIP files are very important, they work in a similar way to WinRAR and are used to compress a folder or several files in Mac and Windows. It is an extremely useful program that will help us compress hundreds of files into one, something very interesting, especially when we have to send several documents by mail or some other application.

What is a ZIP file?

Basically, we can put all the content of a folder in a single file. ZIPs work in the same way as a standard folder, the only difference is that we can just convert 200 files into a single compressed file.

In this way, it becomes much easier to send and receive files. Best of all, in many cases, you can also reduce the size of compressed files, without losing quality.

Are ZIP files dangerous?

In part they can be, this will depend on the files that the container contains. ZIPs are not dangerous, but if a person decides to compress malware and we unzip it without analyzing it with one of the best antiviruses, then it can become dangerous.

Just to clarify, ZIP files themselves are not dangerous. But if a malicious act compresses a file with other malicious files, then it can be a danger to our computer. That is why we must be very careful with what we download from certain websites.
