Strong AES-256 encryption in 7z and ZIP formats.For GZIP and ZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip.In my opinion it’s never a good idea to install a. 7-Zip is in fact a powerful tool, but if all you’ll ever use it for is to unzip the zipped folders your boyfriend sends you then you simply don’t need it.
For example, I select the file “download.txt” Step 1: You choose the file you want to compress.
