# Large Test Archives
Each fixture contains one `large.bin` entry with a 67,108,864-byte (64 MiB)
deterministic, repeated text pattern with a 2 KiB `0xFF` prefix. The entry CRC-32 is
`f9081eb0`.
| Fixture | Archive API | Reader API |
| --- | --- | --- |
| `Large.zip` | Yes | Yes |
| Generated `Large.tar` | Yes | Yes |
| `Large.gz` | Yes | Yes |
| `Large.rar` | Yes | Yes |
| `Large.7z` | Yes | No |
| `Large.tar.gz` | No | Yes |
The compressible payload keeps the compressed fixtures small while requiring a full
64 MiB decompression to validate each API. The tests expand `Large.tar.gz` to a scratch
`Large.tar` before exercising raw TAR support, so the 64 MiB TAR file is not committed.
## Regenerating
The fixtures were created with `zip`, `tar`, `gzip`, RAR 7.22, and 7-Zip. Run these
commands from a temporary directory after replacing `<repo>` with the repository root:
```sh
yes "SharpCompress large fixture" | head -c 67108864 > large.bin
printf '\377%.0s' {1..2048} > prefix.bin
dd if=prefix.bin of=large.bin bs=2048 count=1 conv=notrunc
touch -t 202001010000 large.bin

gzip -9 -c large.bin > <repo>/tests/TestArchives/Archives/Large/Large.gz
