What is a QPJ file?

QPJ files mostly belong to QGIS. QPJ files are used by QGIS to store project configuration data with a focus on projection settings and spatial reference information.
This file type holds details such as the coordinate reference system, map layer alignments, and other configuration parameters vital for geospatial work. It is similar in purpose to companion files (like .prj) found in other GIS software, but is tailored to QGIS projects.
Key points summarized by FilExt.com include:

Project configuration specific to QGIS

Projection and spatial reference data storage

Often in an XML format for easy readability by advanced users

Helps ensure accurate georeferencing across multiple data layers
