4 Steps to Open an Unknown .QZD File

Because .QZD files can originate from different programs, they aren't universally openable.

1. Identify the Source: If received from an educator or trainer, it is likely Quiz Data. If from a developer, it may be a proprietary data dump.
2. Check the Header: Open the file in a text editor or hex viewer to inspect the first bytes.
   • Readable XML/JSON suggests a plain-text structure.
   • "PK" indicates a ZIP archive.
   • Random symbols imply a binary format.
3. Use the Original Software: Opening the file usually requires the original program. Try Luzius Schneider's QuizPro or a standard text editor; if uncertain, ask the sender.
4. Use this Webpage: Drag and drop your .QZD file into our viewer to detect the format, extract readable text/metadata, and preview when possible.

QZD file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. 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 QZD files:

QZD is rarely used as a file extension and is mainly used by one program with a specific format. The file formats most commonly found in QZD files are:

• 97% of all QZD files internally use the ZIP format, so several files are combined and compressed into one QZD file. A QZD file contains 3 to 3 files, the average being 3. Common included file names are \uploadTemp\_DATA.db, \uploadTemp\data.xlsx and \uploadTemp\unitInfo.ini. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. QZD files are between 26 KB and 46 KB in size. Several words can almost always be found in the files, e.g. uploadTemp/ and uploadTemp/data.xlsx. A usual file name is -_-_20180601.qzd or -_-(2025)_20180601.qzd.

The remaining 3% of all QZD files are files with no common format. You can get all the details of your QZD file by dragging it onto this page or by clicking the button "Choose your .qzd file to analyze" above.
