Removing older service packs?

Hi all,

I don't know that this is the right place to ask this question, but I don't see a better place. Can I remove older service packs of Composer XE by just removing the directory (for example, /opt/intel/composer_xe_2013_sp1.1.106 for 14.0.1)? I'm running out of space for all of these compiler versions.

Thanks!
