7-Zip

7-Zip is a software tool that compresses files and folders into smaller, more manageable packages called archives, making them easier to store or share. It supports various formats, including its own highly efficient 7z format, as well as ZIP and RAR. Additionally, 7-Zip can extract files from many different archive types. It’s known for its high compression ratio, meaning it often reduces file sizes more effectively than other tools. Free and open-source, 7-Zip is widely used for saving space and organizing digital files efficiently.
