It contains only original archive-practice.txt (5278 bytes). SHA256 of extracted plain text: c0c867a56136af72687f82cedc32f478bfb3c8117ed8f203b603ade38479d697

Our native 7-Zip26.04 console test: complete set Test exit0, Extract exit0 and identical SHA. A separate set with .002 moved out failed Test exit2: Unexpected end of archive.
