In the Project tool window, select the directory
in which you want to create a new file.
Choose or press Alt+InsertAlt+Insert.
Alternatively, right-click the corresponding directory and select New from the context menu.
Select the desired file type.
Generally, all the options except File and Directory correspond to using a file template.
Note that certain options may correspond to a group of related file templates. For example, if you select to create a class, you'll be able to create a class, interface, etc. or, in other words, use one of the corresponding related file templates.
An existing file template may be missing from the list if this is a custom template whose file name extension (template extension) does not match registered patterns of any of the recognized file types. In such a case, you may want to register the corresponding pattern for an existing recognized file type or add a new file type and register the corresponding pattern for this new type. For more information, see Creating and Registering File Types.
In the dialog that opens, type the name of the file in the corresponding field.
Note that you should not type the file name extension.
Specify other information as required. For example, you may be asked to define the values of custom variables if the corresponding file template contains such variables and their values are not currently set.
