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.
What is the file type 7z?
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.
What are the benefits of 7-Zip?
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.
