extract a specific substring

Hi to all,
I'm an awk newbie.

I have a text file like this:

aaa /home/smith/subfolder1/filename1.ext1 bbb
ccc /home/smith/subfolder1/subfolder2/filename2.ext2 ddd
eee /home/smith/subfolder1/filename3.ext3 fff
::::

I should extract (for further parsing) the filenames above: in other words
the substrings between the LAST slash '/' (excluded) and the last space ' '
(excluded)

filename1.ext1
filename2.ext2
filename3.ext3
:::::

thanks a lot

Marco

awk -F '[ /]' '{print $(NF-1)}'
