These standard CRSs are based on those defined by the European Petroleum Search Group EPSG and the Institut Geographique National de France IGNF and are made available in QGIS through the underlying Proj projection library. When you need to transform a whole batch of files at once from one CRS to another you can do so using the Processing Batch Script method.

We have all grown very accustomed to his Mercator projection but I want to take the chance to explore some alternatives. QGIS also provides a testing tool where we can provide the WGS 84 coordinates and get the coordinates of newly added custom CRS projection.

In this example we had multiple data layers in WGS84 EPSG 4326 and we needed to convert them to an equal area projection in order to run some spatial analysis. When you include a prj file QGIS will automatically assign the proper coordinate or projection system to the shapefile. Working with Projections.
