K42.7z -

For large file sets, 7z provides multi-core compression, making it faster than many single-threaded alternatives. More details on using 7z with block devices ?

The 7z command is a powerful archiving tool that supports multi-threaded compression (LZMA2) and split archiving. Here is a write-up summarizing key technical considerations when using 7z: K42.7z

You can skip compression while still including files by setting the compression level to 0 (store). For large file sets, 7z provides multi-core compression,

Based on your request, "write-up: K42.7z" refers to a technical topic concerning the , specifically focusing on handling, archiving, or automating 7z files. Here is a write-up summarizing key technical considerations

Using algorithms like LZ4 is recommended for data that is already compressed, as it prevents inefficient re-compression and speeds up the process, achieving high compression/decompression speeds.

Scripts (e.g., PERL) can be written to customize compression levels based on file extensions.

Tell gzip/bzip2/7z/etc not to compress already-compressed files?
