Grab the file for your platform from the latest release (Windows installer or portable zip, macOS and Linux tarballs), or build it:
cargo build --release # binaries in target/release/Details, checksums and the pure-Rust build are in Installation.
arca create photos.zip ~/Pictures/trip/ # format comes from the extension
arca list photos.zip # look inside, extract nothing
arca test photos.zip # verify every CRC, write nothing
arca extract photos.zip -o trip/ # unpackMore in the Quick start and the CLI reference.
Measured on one machine and reproducible with bash bench.sh. The benchmarks give the method, every run and where Arca loses.
