Files with the extension SHP contain data in ESRI shapefile format. It is the main file of this standard, which contains the actual geometry data.
For use but usually more files are necessary. Especially the index with the ending shx and the dbf database. There are still optional files eg Atx, sbx, sbn, aih, ain, prj and cpg, which contain further special information, but do not always have to be present.
The ESRI shapefile (shapefile) is a popular spatial vector format for Geographic Information Systems (GIS) developed by ESRI's largely open specification for ArcGIS, which is used to exchange data between various products of ESRI and other manufacturers.
These files are not only used by actual GIS applications, but also by other systems that work with GIS data or forms, eg the CARE-S channel maintenance system.
Most often resolving problems with opening SHP files is very simple. Just install an appropriate program that supports such files. All of the listed programs support SHP files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of SHP files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate SHP files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the CorelCAD applications is not on the list, select "Browse" option in order to manually locate the directory where CorelCAD has been installed.
Sometimes problems with opening SHP files may not lie with the application itself, but can arise due to other causes, such as:
