IntelliJ IDEA 13.1.0 Web Help

The dialog box opens when you attempt to open a file in the editor, but IntelliJ IDEA does not recognize its type by the file extension. Use the dialog box to associate unknown file extensions with existing file types.

Item Description
Open matching files
in IntelliJ IDEA
When this option is selected, IntelliJ IDEA treats the type of the file to be opened as one of the recognized file types. Choose the relevant type from the list box below, that displays all the file types recognized by IntelliJ IDEA.
File Pattern In this text box, specify the file pattern to be associated with the selected file type. By default, the text box shows the following pattern: *.<current file full extension>.
Open matching files in associated application When this option is selected, IntelliJ IDEA attempts to open the selected file using its native application, if this application is available.


You can change the association later in the File Types settings page.
