Who owns 7-Zip? ›

7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. 7-Zip uses its own 7z archive format, but can read and write several other archive formats.

Right-click the file you want to zip, and then select Send to > Compressed (zipped) folder. Open File Explorer and find the compressed folder. To unzip the entire folder, right-click to select Extract All, and then follow the instructions.

WinZip opens and extracts 7z Compressed Archive Files—and many more formats.

When using Windows, it is best to use the 7-Zip tool to open a 7z file. It is a free, open-source tool that makes it easier to view these files. All you need to do is follow the simple steps below. First, download and install the 7-Zip tool on your computer.

Use an online file sharing service and send a link to download the file to your recipient. Split the file into multiple parts to share and the recipient can reconstitute the parts into a single file. A good example of this is the RAR format, of which there are a number of great (free) solutions such as 7-Zip.

Conclusion: For 7ZIP use the *. 7z format with LZMA2 and BZIP2 with the "fastest" setting to obtain 50% compression in a reasonable (fastest) amount of time. Because 7Zip is open source, there should be no issues with compatibilities in the near future.

Right-click (Ctrl-click) the file and choose Compress. A new file will be created on your desktop with a . zip of the same name. If you have several files you need to compress, make a folder with the files you want to compress, and then right-click (Ctrl-click) and Compress.

At only a fraction of the speed of 7z, you will get max. ~30% compression, while there is no way to get up to ~55% compression with ZIP at all. And even at 55% compression with “7z Normal” preset, 7z will be 50% faster than ZIP for ~30% compression performance. Yes, it is that clear.
