and .IDL) when you use Class Wizard to add code to them.

STATUS
======

MORE INFORMATION
================

Steps to Reproduce Behavior
---------------------------

For example, the following steps delete an .IDL file that is in an ATL project:

1. Start a new instance of the Visual Studio IDE.

2. Create a new ATL COM AppWizard Application, DLL server, with the MFC Support
  check box selected (name it test).

3. Go to class view, right-click and add a class named "testObject" (without the
  quotation marks) with interfaces.

4. Go to file view and select Class Wizard from the view menu.

5. Add a New Class from ClassWizard called CTestClass that is derived from a
  generic CWnd and click OK. You receive an error dialog with the following
  message:

  "Unable to update the IDL file "<drive>:\test\test.idl". Make sure the
  file is not read-only and there is sufficient disk space"

  When you dismiss this dialog box, your .idl file is deleted.
