   Because it is not possible to install version 4.52 onto an existing 
desktop it is desirable to somehow automatically move the objects from 
the old desktop over to the new.  Searching on the web the only facility 
that I could find was Object Desktop's "Object packager".  Of course you 
have to have OD installed on both the source desktop and the target 
desktop before you can use the facility.

   I found that I could not simply restore the objects onto the target 
machine.  By forcing the process and inappropriately using Travelling 
Workplace (another story some other time) I wrecked the desktop so badly 
that the only remedy was to reinstall!  What happened was that everytime 
I tried to restore an object I'd get the following popup:

   Well in ignorance I tried Ignore.  The object seemed to be created 
OK.  I then blithely went ahead and did lots of them.  Sometime during 
that process many links got broken and, wildly, some objects properties 
got changes to entirely different files!  Then in the process of trying 
to straighten things out D:\OS2\MDOS and everything in it got deleted 
during a shutdown reboot cycle!!!  So that is what you can get if you 
have "WPS problems"!

   After reinstalling and being pressured to somehow get Object Package 
to work I found that objects could be recreated by OP first producing a 
REXX script.  Then you'd run that.  Some scripts would prompt for 
certain missing classes to be (re)created.  I found it best to choose 
not to re-create.  One of the classes was to re-create an enhanced 
folder class.  But the folder that was to be re-created was already in 
an enhanced folder and would inherit the properties of that enhancement. 
  By trying to double up on "enhancement" the WPS didn't like it at all. 
  I think the WPS hung   :-(

   I think my installation of OD in the source desktop was probably 
faulty but what happened has disappeared into the mists of time.

   Once I got the hang ot creating and running the REXX scripts I could 
quickly recreate/migrate lots of objects without wrecking the new 
desktop.  Very good!   :-)   Additionally, because I wanted to place the 
executables into a more suitable directory structure, I could edit the 
paths in the text file REXX scripts before running them and they'd come 
up with the new properties reflecting the new directory arrangements.

A note about the OS/2 registry
   OS2.ini and OS2Sys.ini are closely connected with a "Desktop" 
directory usually x:\Desktop (where x is the boot drive).  Playing with 
Travelling Workplace which can create up to 36 desktops more desktop 
folders are created usually labeled x:\Desktop1, x:\Desktop2 and so on. 
  Well in confusion at one point I deleted the wrong x:\Desktop# and the 
WPS would not come up, until MAKEINI was run.  Most of the contents on 
the desktop are stored in the registry.  You can populate and depopulate 
the desktop by having a range of registry files with different contents, 
changing which one config.sys points to and rebooting.

   Everytime MAKEINI is run a new desktop directory is created.  Your 
filesystem then loses elegance.  I haven't worked out how to edit the 
registry to point to a renamed directory.
