Creates a new file and opens it. The file appears under the Miscellaneous Files folder.
Syntax
File.NewFile [filename] [/t:templatename] [/editor:editorname]
Arguments
filename
Optional. Name for the file. If no name is supplied, a default name is provided. If no template name is listed, a text file is created.
Switches
/t:templatename
Optional. Specifies the type of file to be created.
The /t:templatename argument syntax mirrors the information found in the New File Dialog Box. Enter the category name followed by a backslash (\) and the template name, and enclose the entire string in quotation marks.
For example, to create a new Visual C++ source file, you would enter the following for the /t:templatename argument.
/t:"Visual C++\C++ File (.cpp)"
The example above indicates that the C++ File template is located under the Visual C++ category in the New File dialog box.
/e:editorname
Optional. Name of the editor in which the file will be opened. If the argument is specified but no editor name is supplied, the Open With dialog box appears.
The /e:editorname argument syntax uses the editor names as they appear in the Open With Dialog Box, enclosed in quotation marks.
For example, to open a file in the source code editor, you would enter the following for the /e:editorname argument.
/e:"Source Code (text) Editor"
Example
This example creates a new web page "test1.htm" and opens it in the source code editor.
>File.NewFile test1 /t:"General\HTML Page" /e:"Source Code (text) Editor"
