I would like to query R for the current (or last used) filename for a

Eg after png(filename="plot%02d.png") I would like something like the

You cannot, it is handled internally and the name is not returned.
So you have to workaround yourself either by specifying filenames yourself
and looping over the png() calls, or counting yourself ...
Or just look on the disk with list.files().
sort(list.files(pattern="plot[0-9][0-9]\\.png"),
decreasing=TRUE)[1]
