: By concatenating files before compressing them, 7-Zip can find patterns across different files that would otherwise be missed if compressed individually.
: Choosing "Non-solid" treats every file as its own block, allowing for faster individual file access and better resilience to corruption.
: To extract a single file from the middle of a solid block, the software must decompress all preceding data in that block, which can be slower than non-solid formats like standard ZIP.
