To find particularly large files on your Mac’s hard disk, the quickest way is to use Finder:

Deleting unused applications is easy in Mac OS X Note that there may be a few preferences files left behind by uninstalled apps, most of which can be found in the ~/ Library / Preferences folder and safely deleted. In Lion it’s made even easier – open Launchpad and hold down the Option key until the icons wiggle, then just click the small white “x” icon that appears next to any app that was installed from the App Store. Uninstalling applications in Mac OS X couldn’t be simpler – just delete the application by moving its icon to the Trash. For example, Pages is 266 MB and iPhoto a whopping 1.1 GB. In Mail, trash and junk emails can be automatically deleted by setting the relevant options in preferences.Īpplications can take up large amounts of space. There’s no need to keep your Mac’s Trash can full, especially if you make regular backups of your files. Remember that individual applications such as iMovie, iPhoto and Mail each have their own Trash, so empty those frequently too.

The most obvious and easy way to free up some space is to empty the Trash.
