Nope -- Interchange doesn't remove any old files. That's up to you, to do 
according to each site's needs.

The session files are ... sessions. :) The tmp files are more-list paging 
files and some other assorted things.

See:

You're using files, not DBM sessions, so look at the examples for purging 
old files. I've attached the little shell script I often use to clear 
session, tmp, and timed (for timed-build output files) files that are more 
than a day old.
