XTree for Windows
Zip 2.0 Update File
===================

Purpose: 
--------
This patch provides Zip 2.0 file extraction capabilities to users
of XTree for Windows version 1.5.  It will not operate on earlier
versions of XTree for Windows.

Once this patch is successfully applied, you will be able to 
extract and view files in Zip 2.0 archive files (in addition 
to Zip 1.1 archive files).  "Multi-floppy" Zip 2.0 files are not 
yet supported.

Installing the Patch:
---------------------
1) Copy the contents of this archive into your XTree for Windows
   program directory (usually C:\XTREEWIN).
2) Close XTree for Windows and quit Windows (or open a DOS window).
   XTree for Windows must not be running when this patch is applied.
3) You may want to make copies of the files listed below on a floppy
   disk.  It is the only way to restore XTree for Windows to its 
   original configuration.

   Files to be updated:  XTREEWIN.EXE
                         XTWZCFS.DLL
                         XTWUZPE.DLL

4) From the DOS prompt, type the word PATCH.  The update process
   is now automatic.

   When the patch is complete, check the following files to make sure
   they are the correct size:

                         XTREEWIN.EXE   83,968 bytes     
                         XTWZCFS.DLL    48,575 bytes     
                         XTWUZPE.DLL    72,535 bytes     

5) The update is now complete.  You can restart XTree for Windows and
   Windows, if necessary.
