How to open 7z files

To open a ZIP archive in 7z file format, it needs the 7-Zip packing program or other unpacking programs like WinZip or WinRAR. We’ll show you how to easily open a 7z file.

If you need to send large or many files or if you need to download them, then you may already be familiar with the common file ex­ten­sions .zip and .rar. The 7-Zip file format with the .7z file extension is also one of the strongest data com­pres­sion formats. 7z files are created with a 7-Zip packing program. The resulting archive files can combine different file formats (com­pressed and un­com­pressed) and also encrypt them. 7-Zip has one of the highest com­pres­sion rates and can reduce original files to about 85 percent of their storage size.

The advantage of the free, open-source packing program 7-Zip is that it is very extensive in its functions. Not only does it let you compress files – it also lets you encrypt them. In addition, it supports numerous formats such as ZIP, TAR, WIM, XZ, GZ, BZ2, APK, DOCX, JAR, RPM, ISO, DMG, FLV, SWF, and DEB for packing and unpacking, as well as RAR, ARJ, CPIO, LZH, LHA, MSI CAB, and EXE for unpacking only. If you want to use the program, you have the choice between an installed and a portable version of 7-Zip.

Two major strengths of 7-Zip: you can create dis­as­sem­bled and self-ex­tract­ing 7z archives, as well as encrypted archives. The ability to split 7z files into sub-archives ensures even faster transfers. The self-ex­tract­ing feature can be used by saving the files as EXE files. You can access the contents im­me­di­ate­ly with a double-click. In turn, the AES en­cryp­tion with 256-bit cipher key length for 7z and ZIP including password pro­tec­tion ensures high security. This is a par­tic­u­lar­ly intuitive and clear method thanks to the file manager and its graphical interface.

Unpacking a 7z file is easiest with the 7-Zip packing program. Since it supports the most common file formats, it’s suitable both for creating ZIP files and for unpacking the most diverse archive files. 7-Zip is therefore par­tic­u­lar­ly powerful and versatile. Since the program is not in­te­grat­ed into Windows, the first step is to download and install the software from a reputable source. After in­stal­la­tion, you can unzip 7z files of your choice simply by right-clicking on “Open with” and selecting “7-Zip” from the available programs.

To open 7z files, you can also use other popular packing programs, for example:

• WinZip for Windows
• WinRAR for Windows
• WinZip Mac Edition
• The Unar­chiv­er for Mac
• TAR for Linux

If you rarely deal with archive files, but urgently want to extract a 7-Zip file without software, you can simply use online tools such as ezyzip.com or extract.me to get the job done. The online unpackers are websites that allow you to upload and extract archive files in 7z format as well. Depending on the tool, you can choose whether you want to pack or unpack files. You can also specify the des­ti­na­tion format and location. This way, you’ll be able to unpack your archive file without much effort and, most im­por­tant­ly, without ad­di­tion­al programs.
