Understanding gz and 7z file formats

GZ (GNU Zip) is a popular compression format primarily used on Unix and Linux systems. It compresses single files and is often used in combination with TAR archives (as .tar.gz) to compress multiple files. 7Z is the native archive format of 7-Zip, an open-source file archiver. It offers high compression ratios and supports advanced features like strong AES-256 encryption and multi-volume archives.

Why convert gz to 7z?

Converting gz files to 7z format can provide better compression, easier multi-file archiving, and improved compatibility with modern archivers. 7z files are also widely supported on Windows, macOS, and Linux.
