In each of the .shp, .shx, and .dbf files, the shapes in each file correspond to each other in sequence (i.e., the first record in the .shp file corresponds to the first record in the .shx and .dbf files, etc.). The .shp and .shx files have various fields with different endianness, so an implementer of the file formats must be very careful to ...
QGIS is a geographic information system (GIS) software that is free and open-source. [2] QGIS supports Windows, macOS, and Linux.

One "shapefile" usually include four different files : .shp, .shx, .dbf, .prj. First three files must all be present in order to use the data. Each shapefile can hold only one geometry type. The projection information contained in the .prj file is critical in order to understand the data contained in the .shp file correctly.
Two strategies have been used to integrate the geometry and attributes into a single vector file format structure: [13] A georelational format stores them as two separate files, with the geometry and attributes of each object being linked by file ordering or a primary key. This was most common from the 1970s through the early 1990s, because GIS ...
