Related: LZIP is better than 7-zip
7-zip is a popular LZMA cross-platform compression algorithm.
7z a huge.7z huge.dat
7z e huge.7z
- enable multithreading (far faster compression)
- enable LZMA2 compression (more advanced)
- like “fast” compression.
Example 7-zip for very large files (100s of gigabytes or terabyte-size files)
7z a -t7z -mx=3 -mmt=on -m0=lzma2 mycomp.7z *.txt
- higher compression settings might not add a lot of compression but can take vastly longer.
