7-Zip » Best Free File Archiver 2020 — 7Zip Help
Welcome to 7-Zip, the best archiving tool that you can find on the internet. If you need your files to be organized and placed on a single compressed file, 7zip can do that for you. You will never need any archiving tool again with the 7zip software.
In all our everyday computing needs, documents, and media files pile up and clutter through time. It creates unwanted chaos especially when you need a document from some years ago that you created and saved on your Windows computer or Macbook with 7Zip. Sure, you can use your operating system’s native search function, but that is only good for a single or a few files. What will help you organize those files is the 7zip archiving tool.
What is 7-Zip?
The 7-Zip archiving tool is the open-source software created by Igor Pavlov back in 1999. This is to address the problem of keeping multiple files organized in one place. Also, though archiving, it also lessens the size of the files in the process without compromising the files’ entire integrity.
7-Zip, as mentioned, is an archiving tool. You can use 7-Zip to create a cabinet of similar files that will help you organize everything. The best thing about file compression is that you lessen the size of the file or files that you archived. This means you will have even more free space for other new and bigger files. The 7zip archiving tool can also be set to group files in one specific archive and protect them by encryption or password. This is very much useful and helpful, especially when sending sensitive data through a network.
Supported Archiving Formats
7-Zip supports many file compression formats. Its native archive format is 7Z which represented by .7z file extension. While 7zip alone can create various archiving formats such as ZIP, RAR, 7Z, Gzip, bzip2, xz, tar, and WIM, it can unpack a lot more different file compression formats. Here’s a list that you can use as a reference: APM, ARJ, CHM, Cpio, DEB, FLV, JAR, LHA/LZH, LZMA, MSLZ, Office Open XML, Onepkg, RAR, RPM, Smzip, SWF, XAR, Z archives, CramFS, DMG, FAT, HFS, ISO, MBR, NTFS, SquashFS, UDF, VHD disk images, NSIS (LZMA), some MSI files, Some Microsoft CAB (LZX compression).
To give you a broader view of what 7zip can actually do and why it is useful for your everyday office-based needs or even home-based tasks, we have listed some of its major features. These features, as you will find, are very much the basic fundamental uses of 7zip.
What It Can Do?

Whether you want a single file or a group of files to be compressed, 7zip can do that for you in different archiving and compression formats that you desire.

Supports Multiple-core CPU Threading
Did you know that 7zip is also used for measuring CPU clock speed in terms of multi-core performance? The 7zip software can utilize multi-core on any CPU, both mobile desktop version, to provide faster and efficient file processing and archiving.

Is it Safe?
Due to its less popular reception and late arrival to the scene, the 7zip is sometimes mistaken as some form of malware. This is natural for those less acquainted users. But the fact to the matter is, 7zip is the safest and most useful tool compared to other popular archiving tools.
In fact, the 7zip software is used by some IT professionals and tech individuals as a manual tool for extracting, identifying, and deleting some types of malware and computer viruses. Unlike the better known WinRAR, which has some serious vulnerabilities for most malware, the 7zip has no known Windows virus that can defeat it.
While its interface may look outdated and too simplified for most people’s taste, it makes up for its usefulness on most archiving, compression, and decompression tasks. So if your question about 7zip and its safety still stands, let us be the one to assure that it is safe in any means and angle possible.
The only reason that we see 7zip being not safe software is if you downloaded it from an unofficial source. We all know that anyone can rename a file or any software and brand it as 7zip. So to be able to make sure that you are using the original and safe version of 7zip, kindly get your installer from a trusted source such as from this site or from 7zip’s official website. www.7zip.org.
Use 7-Zip for All Your Archiving Needs
If you regularly deal with all sorts of files, do not just use a folder to organize them. Folders are easily hacked and accessed by any person even the non-techy ones. To be more safe and secure, use 7Zip to organize your files and make them encrypted using your own preferred password. Plus, you get to save more hard drive spaces the more you use it.
We highly recommend using 7Zip in your everyday use. Choosing this archiving tool as your primary cabinet or folder in your computing machine makes a lot of difference especially in the long run.
