Every now and then, your computer – in my case, a Dell Inspiron E510 – will need some TLC. Freeing up disk space and running defrag can go a long way to keeping your system running better. I spent an hour or so yesterday doing some housekeeping and ended up deleting over 45+ gigabytes of old videos, unused applications and more. Today, my system feels zippier and more responsive. All of my core applications – Photoshop, Illustrator, Dreamweaver – are running better than usual. Consider this a friendly nudge to do the same on your own computer, if you’re not already doing it.
