Photoshop :: Auto Metadata

Is there a way I can set PS to autosave some preset metadata every time I create a new drawing or update some photo or photoart? I want it so save into the file somewhere, my name as the creator. I am trying to do this will all my programs that allow me to save a file that I create. This way if I ever need to back up all my personal files again I can search for all files that have me as the Creator or Author and back them up all at once. My intention is always to set up folders such as My Photos, My Art, My Word Docs, My Excel, etc... and save every media I create in these and I can never seem to keep up with this and my files end up everywhere. The my Hard Drive fills up or I want to clean my PC and finding all my files is a challenge and time consuming.
