Drag from my app to others?

I have a batch type application with two lists. The top one is the list of files to be processed and the bottom one is the list of the output files. (with some other status info) I would like the ability to drag the files from the bottom list out into Windows and drop them into other applications that will accept that file type. Is that possible? I've found a million tutorials about how to drag files in to your program, but I can't seem to find any on how to drag out of your program.

Thanks,
Dan
