Hello I need to join multiple flash movies and convert into one

and i have a couple avi's that i would need to convert to fla also.

then i would display on web site. would anyone happen to know about free software out there to do this?

thanks

If you have the original Flash movies you could cut and past the frames into one movie then publish it to SWF, but as far as AVI's are concerned (depending on your version of Flash), you MAY be able to import them into Flash.
