Tell gzip/bzip2/7z/etc not to compress already-compressed files?
7z allows for non-solid mode, which is beneficial when specific files within a large archive need to be accessed quickly, as it reduces the need to decompress the entire archive. K42.7z
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
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. K42.7z
Scripts (e.g., PERL) can be written to customize compression levels based on file extensions.
