How to get full path for traces in a graph

I have few traces on a graph (plotted waves are in different folders), want to do some processing while preserving the original waves. So, I want to write a function which can do the custom processing I need on the traces in the graph. For that I wanted to copy the X and Y waves on the graph to a folder named, say, "analysis". So for that (and for other purposes also in future) I wanted to get the "full path" to the traces in the graph. I am trying this since last few days but failed to figure out. I am aware of the function "WaveRefIndexed" but I can only change the wave in the trace using this, cannot use it to copy the wave. One solution is to copy the waves manually in one folder and then use the function "WaveName". But this is not an efficient method for me as I use lot of folders and traces from them on the same graph for comparison. I hope there is method to achieve this in Igor. Any help is greatly appreciated.
