Thanks. I have tried what you say, but though the click botton is there it does not seem to do anything. Of course, I have already gone thru the list of app+programs and deleted everything I could. My concern now is the op.system. When you look at properties, in file manager, for "windows" directory it says:
size= 19.1Gb size in disk= 12.3 Gb Contains= 112,662 files 21,994 folders
I am sure I could shift a lot of it to my external HHD and free up space.
Perhaps I will ask Microsoft.
Thanks anyway.
