By default, all software supports multiple file extensions. IntelliJ IDEA supports at least 7 different file extensions. The basic files that IntelliJ IDEA supports are .APK. However, not all of the extensions listed on the list are always used to save the effects of work in IntelliJ IDEA. Very often, files with such extensions are used as source data files used by IntelliJ IDEA.
IntelliJ IDEA can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via IntelliJ IDEA and try to save it in another file format, also supported by IntelliJ IDEA.
