Cleaning up old ableton files

[swett]

I just installed version 8.3.4. I've been using Live since version 5 i think, and on this MacBook Pro for a couple of versions without digging to clean up much of the older version's stuff.
Just curious if anyone knows where and how i should go to delete any unnecessary older Live files that are left hidden around my hard drive. I'm trying to clean up this thing and give it a little more elbow room before Ableton 9 comes out.

Thank you,
B.
