KB10813 - .prj file and naming convention.

The .prj file, which was originally designed to hold the coordinate system information (i.e., projection) for a Shapefile (.shp format vector map file), can be associated to any vector or image map layer. In such case, the layer is rendered to the coordinate system provided by the associated .prj file.

The proper .prj file naming convention must be followed. The name of the associated .prj file must be as filename.ext.prj. Some examples:

file name .prj file name
filename.ext filename.ext.prj
filename.jpg filename.jpg.prj
filename.png filename.png.prj
filename.dxf filename.dxf.prj
filename.shp filename.prj (exception!)

A layer must be georeferenced to work properly with the .prj file. For more information, refer to KB10389.
