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.
