To customize this "deep" post for your exact needs, tell me:
: Use fully qualified file paths (useful for maintaining full structure). -x : Exclude specific files or folders (e.g., -x!*.log ). BTB.7z
Set high (e.g., 64MB or 128MB) for large files—requires more RAM. To customize this "deep" post for your exact
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). 7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on
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
-v1g : Splits the output into 1GB chunks ( BTB.7z.001 , BTB.7z.002 , etc.). Summary of Advanced Switches : Recursively include subfolders.
LZMA2 (optimal for multi-core processors) or LZMA.
