To make the archive secure, you must use . Password: Use a strong, complex passphrase.
Creating a deep, secure, or complex archive with (BTB.7z) goes beyond just "zipping" files. It involves maximizing compression, implementing strong encryption, and preserving complex directory structures. 1. The "Deep" Approach: Maximizing Compression (GUI)
Set to "Solid" or a high number to treat files as one continuous stream, significantly improving compression for many small files. 2. The "Deep" Approach: Security & Encryption BTB.7z
For automation, scripting, or handling advanced structures, the CLI ( 7z.exe ) is best.
7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on -p -mhe=on BTB.7z "C:\Your\Files" Use code with caution. Copied to clipboard -mx=9 : Level 9 (Ultra) compression. -ms=on : Enable solid compression. -p : Prompts for a password (hidden typing). -mhe=on : Encrypts header (filenames). To make the archive secure, you must use

If you need to compress massive files or want the smallest possible size, use these settings in the dialog: Archive Format: 7z. Compression Level: Ultra (highest possible compression).
