The default file extension used on Windows computers for representing non-animated cursors is CUR. This format resembles ICO, but they feature different identification bytes and specifications of a hotspot in the cursor file's header.
Users have the possibility to create custom CUR files that will be installed whenever they create a new theme for their computer.
Creating CUR files can be achieved by encoding regular images to CUR format using specialized graphic converters.
Considering CUR files typically contain several frames, CUR creators will require users to select multiple objects for their output file.
