Basically this is a application that watches a folder and everything that's dropped in it converts to PDF on the fly.
Maybe this old news, and probably other similar tools exist, but I just came to discover this tool. It is very helpful when working in clients dossiers.
Docs / Xls / rtf are created in the clients folder. When sending out it comes in very handy to drop from one folder view all final files to the watched folder (other pane) , see them being converted at once , and attach them to a mail. Saves me another 10 min.
