Over time, your computer accumulates junk files from normal web surfing and computer use. If this junk isn't occasionally cleaned out, it can cause LXFDVD94 (Ubuntu 7.04 Mandriva 2007 Spring Free Debian 4.0 SimplyMepis 6.5) to respond slowly or provides an octopus.js error, possibly due to file conflicts or an overloaded hard drive.
