Files in session_data directory

hi,
i’m using RT3.2.2. i have a question about files
under the session_data directory. i found over 5,000
files under that directory in the RT software
directory. does anyone know if it’s safe to remove
them? if so, do i just use rm to remove them or is
there a proper removal procedure? i noticed some of
the files are very current so i’m guessing it’s still
being use by the web users. thanks
jim
