AES, the Advanced Encryption Standard, came to be as the result of a three-year competition sponsored by the U.S. If you have important security requirements for your data, you should use WinZip's AES encryption. WinZip offers two kinds of encryption: strong AES encryption and weak Zip 2.0 (Legacy) encryption.

CorelDRAW Graphics Suite 2021 (Windows/Mac).With more time 7-Zip makes even smaller files.ĭecompressing rar files is faster with both programs though. But trades some compression for speed.ħ-Zip makes slightly smaller file than WinRAR in slightly shorter time. The powershell will tell how long it took.ħ-Zip is fastest to compress when aiming to speed. Want to test this yourself? Just use powershell and run command Measure-Command for WinRAR. I guess HDD can't feed data to CPU fast enough and reading smaller more compressed file is faster, except 7z files were much slower to open.

Decompressing rar files took 2.7-3.5 seconds, higher compression decompressed faster. Decompressing 7z files took 6.5-7.7 seconds, higher compression decompressed faster. There wasn't much difference between the two programs. All the lower quality settings reached 100% on all cores but these two didn't go above 45%. 7-Zip maximum and ultra take long time for slightly smaller file. 7-Zip normal is a bit slower than any WinRAR setting but also compresses more. 7-Zip fast takes about same time as WinRar fast but compress slightly more than any WinRar setting. 7-Zip fastest is faster than WinRar fastest but has lower compression. The results are quite similar to the older results. Results: (ordered from fastest to slowest) Only compression quality was changed, all other settings were at their defaults in all tests. But we'll see how it goes.ħ-Zip compressed to 7z. This hardware is weaker than hwat they used on that tom's hardware test. Sytem: OS: Win 10 CPU: AMD Phenom II x4 955 RAM: 4 GB HDD: WD Blue 7200 rpm The folder contained 328 files (mostly pdf but some other too). I compressed a folder and timed the compression time. I decided to do quick tests to see if updates to these programs have changed anything. There is this benchmark but it is many years old already.

And as usual people argued a bit about using either WinRAR or 7-Zip. There was again one of those 'must have programs' post somewhere.
