To use IntKey files you must first install a copy of IntKey on your computer. Intkey is part of the Delta taxonomic database software which is available (free) in two versions. a java version for Windows, Mac OS and Linux from the Atlas of Living Australia and the original CSIRO software (Windows only).

The following introduction to the Delta software with some 2025 updates might also be useful.
