How to make compressed files as small as possible 5 tips can be solved

Since you have chosen compression, you naturally hope that the smaller the compression, the better. How can you compress the compressed file as small as possible? Here are some tips for compressing compressed files as small as possible:

1. Select the correct compression algorithm: different compression algorithms have different compression efficiency and speed. Generally, newer algorithms (such as 7z, RAR5, etc.) can provide better compression rates, but it also takes longer to complete compression. If you only care about speed rather than compression ratio, you can use older but faster algorithms such as ZIP or LZMA2.
2. Clean files before compression: Before compressing files, you can delete all unnecessary, duplicate or outdated files, which can reduce the amount of data to be compressed and improve the compression ratio.
3. Split into multiple volumes: If you need to store large files or folders, you can split them into multiple smaller files. This will make it easier to transfer and back up files and make better use of storage space.
4. Adjust compression level: Most compression software allows you to set the compression level to control the balance between compression rate and compression speed. Generally, a higher compression level will provide a better compression ratio, but it will take longer to compress.
5. Use password protection: Adding password protection can prevent unauthorized access to the contents of the compressed file, but it may have a certain impact on the compression rate.

Note that not all files can be compressed to achieve a smaller file size. For example, files that have already been compressed (such as JPEG or MP3) usually cannot be compressed any smaller. In addition, the compression ratio is also affected by factors such as file type, data density and compression algorithm.
