What is a QMD file

QMD files mostly belong to QGIS/Quarto. QMD files can refer to different file types depending on the software that created them.

QGIS Project Metadata File: Contains configuration details and metadata for a QGIS project. Its content is in HTML format, which helps the GIS software load project settings.

Quarto Markdown Document: A plain text file that mixes markdown with code chunks. It is used in the Quarto ecosystem, often with RStudio, and is geared toward literate programming and dynamic document creation. More details can be found at Posit and Quarto.

Market/Scientific Data File: Stores data used by applications like QuantShare for market data or by scientific tools for quantitative microbial information. Such files are structured for specific data analysis tasks. See QuantShare for reference.

FilExt.com tip: To determine how to open your QMD file, check its content. Look for HTML tags that suggest a QGIS metadata file, markdown syntax typical of Quarto files, or a specific data layout for market/scientific datasets.
