What is the .OFN File Extension?

.OFN File Extension Description:

HKEY_CLASSES_ROOT is the section of the Registry that controls all the data files on the system and handles keys that includes all the file extensions and associations of executable files. It also determines how an application will react when a document file is double-clicked.

The OFN file extension is one of the many entries in the HKEY_CLASSES_ROOT section. It is associated with the Office.FileNew documents of Microsoft Office. Some of the file extensions inside this section associated with Office files are the following:

* OBD - Office.Binder.95

* OBT - Office.Binder.Template

* OBZ - Office.Binder.Wizard

* DOC - WordDocument

* RTF - Word.RTF

* XLS - Excel.Sheet.5

* WBK - Word.Backup

When new document templates are created, they are stored in a hidden subdirectory to the Windows directory called ShellNew. However, these templates are saved in an empty document using your application which is then provided with a ShellNew subkey to the Registry entry for the application's file extension. A value named FileName is then added, which holds a string that gives the name of the template you have created.

The ShellNew subkey presents different options of creating new document templates and one of them is by using the Command value. When the user chooses a new document of this type from the menu, the program specified is run, if the Command value is present.

This option was adopted in Microsoft Office 95. A file type with the file extension OFN is created in the Registry, given the internal name of Office.FileNew, and the "Other Office Documents" as its description.

When "Other Office Documents" is selected from the menu, the msow.exe program is run. The msow.exe module controls the Open and New commands on the Office Shortcut Bar and Start menu. This module presents a tabbed dialog that shows all the document templates available.

If the OFN file extension is selected, it is opened in the Office application allowing the user to save the new document to the correct location by using the "Save As" option.
