[1] FALSE FALSE file.copy looks much more reasonable, except that files "dest1" and "dest2" are still created (despite the fact that "toto1" and "toto2" don't exist). If the 'to' argument is not a dir:

[1] TRUE TRUE !!?!? May be those are (undocumented) features, but I bet 99.9% of the users would expect something different... Cheers, H.
