Carlson 2016 project path re-mapping?

Is there a utility available for re-mapping project paths that are embedded in drawings, and other files withing the project directory structure?

Our company had a standard directory set up with folders for images, GIS data, etc. two years ago. These directory paths have been refined, with the result that some of the older projects have duplicate directory folders now cluttering up the project. I could simply move the files to the updated folder locations, but then I would have to re-map the paths from within each drawing. I'm hoping that there is a way to re-map the paths to image insertions, xref insertions, etc. that could be done for all files within the project directory, not just one at a time from within each .dwg file.
