: A notable "hidden" feature is 7-Zip's ability to switch to a slow sequential mode if it detects inconsistencies between the central directory and local file headers. This ensures it can still extract data even from corrupted or non-standard ZIP files that other tools might fail to open.

: This feature allows 7-Zip to treat multiple files as a single continuous data block, leading to much higher compression ratios than standard ZIP. Note that in solid blocks, individual file "packed sizes" are often displayed as zero because they are part of one large compressed unit.

: The native 7z format uses the BCJ2 coder for executable files, which significantly improves compression ratios for .exe files by using four separate pack streams.
