Opening QDC Files

The QDC file type is primarily associated with ATLAS.ti / Garmin BaseCamp.

QDC	File extension: QDC
	File type:	XML data file

What is a QDC file?

QDC files mostly belong to ATLAS.ti / Garmin BaseCamp. QDC files serve two main purposes. In many cases, they are used as an XML-based qualitative data codebook. This means the file stores codes, definitions, and relationships used during qualitative research. Researchers working with tools like ATLAS.ti or the NVivo platform (as noted by Lumivero) rely on these files. They help keep track of coding schemes in a structured format.
In other cases, QDC files represent Garmin QuickDraw Contours. These files hold cartographic contour data used for mapping. Users can view these maps in Garmin BaseCamp, which provides navigation and terrain visualization.
Key points summarized by FilExt.com include:

The qualitative codebook version is in XML, making it human-readable and customizable.

The Garmin version is used to display contour lines for better map details.

Proper software is required to access all features of each file type.

Simple text editors can show the underlying XML, but native applications reveal the full data structure.

How to open a QDC file

You need a suitable software like ATLAS.ti / Garmin BaseCamp to open a QDC 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 QDC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a QDC file directly in the browser:. Just drag the file onto this browser window and drop it.

QDC file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the QDC files is as follows:

The QDC file type mainly uses a special format. However, the following two file formats are common:

80% of all QDC files internally utilize the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are text files and can therefore be read using a text editor. The files are 2 KB to 45 KB in size, with a median of 11 KB. This file type is new and state-of-the-art. The files contain the following words: <?xml version="1.0" encoding="utf-8"?> and <?xml version="1.0" encoding="UTF-8"?><CodeBook xmlns="urn:QDA-XML:codebook:0:4" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:QDA-XML:codebook:0:4 Codebook.xsd" origin. These files are often associated with codebook, thesis, interview, project, master, maxqda, demo, entrevistas and analysis.
15% of all QDC files belong to Garmin Quickdraw Contours data. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. Most of these files are 110 KB to 370 KB in size. The following keywords are characteristic: AND ITS SUBSIDIARIES, COPYRIGHT, GARMIN LTD and GARMNQDC.

All other QDC files (5%) have different formats. They are often associated with nvivo, coding, interviews, codesystem, codigos, bachelor, analyse, codes, quali, study or year. Just click the "Choose your .qdc file to analyze" button on this page to find out what your QDC file is.

How to solve problems with QDC files

Associate the QDC file extension with the correct application.
Update your software that should actually open xml data files. Because only the current version supports the latest QDC file format. Search, therefore, e.g. on the manufacturer website after an available ATLAS.ti / Garmin BaseCamp update.
To make sure that your QDC file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
