7-Zip – the book
7-zip power user guide, the Ultimate Power-User cheat sheet & mini-course
For many years I used 7-Zip almost every single day in banking IT.
Not only the basic right-click compress stuff, the real power-user tricks that saved us hours every week and kept multi-gigabyte sensitive data 100 % secure.
In 2025 I finally put everything into one single 7-zip power user guide.
Here’s just a taste of what’s inside the mini-course:
How to get much smaller archives than Windows’ built-in ZIP
AES-256 encryption, stronger than most paid tools
Create self-extracting, password-protected, archives (perfect for safe USB/email transfers)
Split huge files into multiple smaller files
The hidden store-only method for lightning-fast backups of already-compressed files
And, of course, we take a look at the command line interface.
No fluff, no filler, only what actually matters in real life.
Plus a detailed explanation of the entire GUI.
Instant download – one-time $5

You’ll never need to Google how to 7-Zip again.
No more trial-and-error.
