I have hundreds of figures with filenames containing "#" to include using \includegraphics, I've tried packages like grffile or currfile, but none of them work. Can anyone suggest a real solution so that I don't need to change hundreds of file names? Thanks.  Update: 1. I'm using Windows. 2. When I compile it, it shows "Illegal parameter number in definition"
