SUMMARY
=======

Microsoft Windows File Manager and Microsoft Windows for Workgroups File Manager
both support add-on extensions.

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

Extensions are special dynamic-link libraries (DLLs) that can be added to the
Windows 3.1 File Manager menu or the Windows for Workgroups File Manager
toolbar. To install these extensions, edit the WINFILE.INI file based on the
example listed below. The .DLL files normally reside in the Windows SYSTEM
subdirectory.

Example
-------

To integrate Mail and File Manager utilities with File Manager, add the ADDONS=
entry in the [SETTINGS] section of the WINFILE.INI. In addition, add a section
called [ADDONS] and the appropriate extensions to the WINFILE.INI. WINFILE.INI:

  [Settings]
  Addons=Mail,FMUtils
   :
   :
  [Addons]
  Mail Extensions=C:\WINDOWS\SYSTEM\SENDFILE.DLL
  FMUtils Extensions=C:\WINDOWS\SYSTEM\FMUTILS.DLL

If File Manager cannot load or set up an extension, no error message is
displayed, and File Manager removes the extension from the toolbar or menu.

These entries provide additional options on the File Manager menu or toolbar,
depending on the version of Windows you are using.

NOTES:

- In Windows 3.1 and Windows for Workgroups 3.11, the maximum number of DLLs
  that you can add to File Manager is six; however, one of those DLLs must be
  the Undelete feature. If you do not add Undelete, the maximum number of DLLs
  is five.

- In Windows for Workgroups 3.1, the Maximum number of DLLs that you can add to
  File Manager is five; however one of those DLLs must be the Undelete feature.
  If you do not add Undelete, the maximum numberof DLLs is four.

The .DLL files used in the above example are found in the following products:

SENDFILE.DLL
------------

Windows for Workgroups version 3.1 Disk 7 (3.5-inch disks)
Windows for Workgroups version 3.1 Disk 8 (5.25-inch disks)

FMUTILS.DLL
