IntelliJ IDEA 12.1.0 Web Help

IntelliJ IDEA recognizes numerous file types. Each file type is denoted with a special icon. Custom files types are also allowed. Each file type is associated with one or more extensions that match a certain pattern.

The file types and their extensions are configurable in the File Types dialog.

Note

"Recognized" does not mean "supplied with extensive support". For example, php files are recognized in the Community Edition and marked with the corresponding icon, although the edition does not provide PHP development support.

The default types include:
