The .gsp file extension is used for a proprietary data file format, which was developed by Key Curriculum Press. The GSP file format is used for files that are generated by Geometer's Sketchpad, which is an educational software that was also developed by Key Curriculum Press. This program provides Windows users with exploration functions and construction tools that can allow them to understand mathematical concepts.These GSP files are also known as Geometer's Sketchpad material files. These are generated by the Geometer's Sketchpad software when users store material data for a project. This material data is saved in these .gsp files.It's recommended to only open these .gsp files using the Geometers Sketchpad program. These do not contain any human-readable data, and the content of these GSP files can only be used by the Geometer's Sketchpad software. By leaving these .gsp files alone, Geometer's Sketchpad can properly display the project that the GSP file is associated with.
