Is there a way to retrieve the file send event...and if possible replace the event?. I would like to make a automatic zip plugin wich zips the files except the extensions in the exclusion list. The only thing is don't know how to find out when the user wants to send something(and what he/she is sending).

Can somebody help me with this?

btw I know there's already a plugin for this,...I just wanna make my own

you can subclass the IM Window and get the message when the file send button is pressed or a file is fragged onto the converstation.  It was fone it File Transfer Plus
