Best Archive Utility

If you work with Mac or Linux, you could use a.tar format instead. 7z is the least supported — it’s not integrated into any operating system, so you’ll have to install an application to open.7z archives. But, if you want the best compression ratio possible, 7z is the way to go. All compression benchmarks are rough. Some may already be familiar with 7-Zip as an archive utility tool but it offers much more than that. 7-Zip compresses files to reduce storage space and increase transmission speed.
