- Description
- A 7Z file is a type of compressed archive that uses the open-source LZMA compression algorithm to reduce the size of the file. This type of file is often used to store multiple directories and files in a single, compressed package. 7Z files can also include strong AES-256 encryption for added security. They are commonly created using the 7-Zip utility developed by Igor Pavlov.
- WinZip, starting with version 12.1, uses the extension .zipx for ZIP files that use compression methods newer than DEFLATE; specifically, methods BZip, LZMA, PPMd, Jpeg and Wavpack. The last 2 are applied to appropriate file types when "Best method" compression is selected.
