Warning: Hash files ... not found

Hello all,
this is probably a standard question but I could not find anything relevant using the search nor elsewhere ...
My "wsusofflineupdate.log" file is full of messages like the following:
Warning: Hash files ..\md\hashes-win-glb.txt and ..\md\hashes-win.txt not found
How can I get rid of these messages or where can I find these hash text files?
One such message per installed patch makes the log file very hard to read.
Thanks for your help.
