Suppose you want to handle a document type with extension .xyz through WindowsEnabler. Right-click a document with extension .xyz in the Windows Explorer. You see a pop-up menu. This pop-up menu should contain an option named open. Select the option named open. The behavior that you now see is the same behavior that WindowsEnabler will show when it opens, views or edits a document. If an open option is not available you cannot open, view or edit the document directly through WindowsEnabler. You could try to explicitly call the required application.
If the menu does not contain an option open, you can not open, view or edit these documents using WindowsEnabler document requests or internal command requests.
