What you need is regex backreferences.. Basically speaking, it's just
grouping parts of a regular expression together using round brackets and
then referencing them.

Please use as regex:

        ([^_]+)_(.+)\.

and for replacement:

        \2.
        
([^_]+) stands for at least one char different from _, (.+)\. is for any
string ending with .

\2. means: replace the matched string with the second matched group and
dot.


This solution is not bullet-proof, but should work for any filename with
extension.
