Startup Disk Almost Full
What am I missing? I've moved and deleted thousands of photos, emptied iPhoto trash and emptied the Trash. Deleted apps that were old versions and have since been updated. Am I really that full, or am I missing something else that I should be doing when trying to free up space? I am using the 'secure empty trash' function, if that is important to know.
As always - thanks in advance from a Mac-loving user who understands little about how they work!
