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.

How to open a QZA file

You need a suitable software like QIIME 2 to open a QZA file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your QZA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a QZA file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert QZA files:

QIIME 2
See the previous paragraphs to learn more about the main application. QZA files are often referred to as QIIME 2 data files because this type of file is primarily created or used by this software.
QIIME 2
A .QZA file is a QIIME 2 Artifact, which is a ZIP archive containing data and metadata related to an analysis step in QIIME 2. It encapsulates not only the data itself, but also the provenance and processing history, ensuring reproducibility and transparency. The standardized format facilitates data sharing and integration within the QIIME 2 ecosystem. This file format is classified as Bioinformatics/Microbiome Analysis.

QZA file format:

If you can determine the file format, the associated program can also be determined. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the QZA files:

QZA is rarely used as a file extension and mainly uses a special format. The two most popular formats are as follows:

97% of all QZA files use ZIP compression, that is, a QZA file includes multiple compressed files. Such a ZIP file contains 8 to 70 files. If you'd like to see the images and files included, just rename the file extension to .zip and double-click. QZA files can be up to 280 MB in size, but are often around 36 KB - 21 MB. The following keywords are characteristic: metadata, yaml, checksums and VERSION. An example of a file name is TABLE.qza. These files can be linked to tree, seqs, rooted, taxonomy, prjna, vector, classifier, feature and results.

The remaining 3% of all QZA files are different files with different signatures. These files are often connected to silva, bray, homd, distance, matrix or dada. Drag & drop your file here to see the file format and a preview of your QZA file!

How to solve problems with QZA files

Associate the QZA file extension with the correct application.
Update your software that should actually open compressed archives. Because only the current version supports the latest QZA file format. Search, therefore, e.g. on the manufacturer website after an available QIIME 2 update.
To make sure that your QZA file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
