Compression level
You can increase the compression level of 7z by configuring the program's options. The compression level and method can be customized as well. The default method is LZMA, which offers excellent compression ratio and decompression speed. Advanced settings can be chosen to maximize the compression ratio. Another option is PPMD, which stands for prediction by partial matching. BZip2 is an older compression method and is not as fast as LZMA.
To change the compression level, right-click selected files and select "7 Zip" from the context menu. You can also choose a different file extension. For example, '7z' will create a file that has a size of 10K, 15K, and 2M, which will create three separate volumes of different sizes. Another option is the -sfx switch, which creates a self-extracting archive.
Although the default setting is 'Compression level', you can change the level manually to 'Auto', "Normal", or "Fast". All of these settings are available through the program's settings menu. The fastest setting is 7z Fast, which boasts a 5x faster compression ratio than ZIP. However, 7z Save wraps files in a single archive at full drive speed, while the remaining levels offer minimal performance gains.

Encryption
To encrypt files in 7Zip, follow these steps. First, right-click on the file and select "Properties" from the context menu. Select the "Encrypt" option. Now, choose the "AES-256" encryption method from the drop-down list. Now, you will be able to see the password and choose whether you want to use the ZipCrypto or AES-256 encryption methods.

Next, you should use a different password for each 7-Zip encryption file. Using the same password across multiple files will expose the files to hackers. To avoid this, use a different password for each account. Even if the 7-Zip encryption code is stored in one location, you should use a separate password for each account. This will reduce the risk of having your 7zip account compromised. Once your 7zip account is compromised, it will also compromise all other accounts on your computer.
