Symbol library moved, any way to update images symbol links to point to the new location?

We created lots of images using the symbols library. We eventually renamed it and moved it to a network drive where everybody shares the same library. Now none of the symbols are linked correctly to the libraries. Is there a way to batch find & replace the old location with the new location so the links still work and I can update the symbols?

I looked inside the .des file and there is a content\data\ folder with a Symbols.dat. Any idea on how to edit the .des files to find & replace the old symbols library location with the new location?
