Sample 7z file (stored)
A valid .7z archive holding three files, including one in a subdirectory. Entries use the Copy codec, so they are stored rather than compressed.

What this file catchesExtractors and upload filters that accept .7z by extension without being able to read one. The format is laid out back to front - the signature header points at metadata that sits after the payload - so a truncated download fails in a way ZIP does not. Extracts with 7-Zip, p7zip and py7zr, and each entry carries its own CRC32, so corruption is detected per file rather than for the archive as a whole.
