From the developer:
PasteFiler is a tool to integrate your Clipboard with the Finder. It is easy to copy data from some application to the Clipboard, but hard to get that data in the Clipboard into its own file. If you have a file that you want to put into the Clipboard, you have to pick the best application to open that file, copy the data, and the quit that application.
