The 7Z file extension is a compressed archive format developed by Igor Pavlov. It can store multiple files into a compressed container with no loss of data, making it an efficient and popular way to store large amounts of data. The 7Z format was initially supported by 7-Zip, but over time, other software programs and compression programs have adopted the 7Z format such as PeaZip, WinRAR, WinZip, and others.
Compression Algorithm
The 7Z file compression algorithm is based on Lempel-Ziv-Markov chain algorithm (LZMA), employing a dictionary compresssion method that matches combinations of characters with replacements of strings that are more common in the original set. This helps reduce the overall size of the file while retainng data and preserving the integrity of the compressed file. The LZMA encoder utilizes full range of algorithms, allowing for increased compression when compared to other formats like ZIP. It can make7z files larger than 4GB, which is not even possible with ZIP compression.
Similar File Formats
Other similar file formats that utilize data compression include .RAR, .TAR, .GZIP, .BZ2, and .XZ. However, 7Z files generally provide higher levels of compression than any other formats.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .7Z) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .7Z extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .7Z file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .7Z extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .7Z extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .7Z file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .7Z file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .7Z file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .7Z file) will be extended to the maximum.
It is also good to check
- if the .7Z file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
