Files that contain the .skp file extension are used by Google's SketchUp 3-D modeling software application. These files contain three-dimensional models that have been created with the SketchUp software program.
The models that are created in SketchUp can be used in the Google Earth application or can be shared with other users online. When 3-D models are created with this software, they are saved using the .skp file extension.
The SketchUp software was initially developed by the @LastSoftware company, but was purchased by Google in 2006.
The .skp file extension has also been used with the Sage accounting software. The SKP files that are used by this software contain saved print files that have been created using the Sage application.

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the SKP file format or software that uses files with the SKP suffix, please do get in touch - we would love hearing from you.
