A 7z file is a compressed archive created using the 7-Zip software application. It is based on the open-source Lempel-Ziv-Markov chain algorithm and uses a variety of algorithms, including LZMA and LZMA2, for high compression levels. The format was developed as an alternative to proprietary formats like RAR, ZIP, and ARJ.What is a 7z file?
