What is a QZA file?

QZA files mostly belong to QIIME 2. QZA files are QIIME 2 artifacts stored in a ZIP format. They package analysis results along with metadata in a structured way, ensuring the reproducibility of microbiome research.
These files include a manifest (typically in JSON) and internal directories that record how data was processed.
Key functions:

Store sequence data and feature tables

Keep detailed provenance records

Integrate with QIIME 2 analysis workflows

Open QZA files using QIIME 2 command line or graphical tools. Avoid generic ZIP extractors as they may not preserve the file's internal structure.
