Thanks again Phil.
I can see how you would assume that this would meet my requirement,
however the purpose of wanting all the copies in a folder, with no
subfolders is to enable me to use IrfanView to make a single image
contact sheet of all the image files, thus creating an index image
that enables the viewer, who knows what image they are looking for,
to ascertain the filename.
I think that IrfanView would require all the images to be in the same
folder.
The copied files would be coming from an archive where the images are
categorized in apropriately named subfolders.
Maybe there is another program that I can use to create a
"contact-sheet" type image from a hierarchy.
