So as long as you're dumping extensions, you can rename the files as you go.
There really are a couple of programs that do exactly this.. (you can use a variety of filters to aid in the process -- they work best if there is some similarity in the current file names to build out the correct filter) The OP should try the Google search I suggested to locate one of these cool pieces of software..
