　How does 7-zip software compress a large file to the smallest size?

First, download and install the 7-zip software on your computer. Then, right-click the file to be compressed, view the source file size and record it. Then, right-click on the file again and select 7-zip-Add to archive. A window will pop up saying "Add to compressed package".

2. Then we set the compression format in the compression window, select maximum compression for the compression level, and select 7z for the compression format. Generally speaking, this format has the highest compression ratio and can compress the file as much as possible. Whether to encrypt or modify the compression path can be set according to your own needs. Here, the editor chooses the default option and does not make any changes. After setting it, we click OK. The software will compress the file. We just need to wait patiently.

3. After the compression is completed, we find the compressed package, right-click and click Properties. Here we see that the file size is much smaller than before. If you still want to shrink the compressed package, it will easily cause file damage, so users should choose carefully.

4. Also using 7-zip compression, we compress the files in .zip format. Finally, the compression is completed. We can check the file size again. It can be clearly seen that the same file compression using 7z format can compress the file into a smaller size. If you need to compress large files as small as possible, you might as well try this method.
