If there's one thing that leaves me scratching my head with OS X's Finder, it's the lack of a display for the size of folders and subsequent files within them. It drives me crazy.
Yesterday, on LifeHacker
, there was a snazzy little tip that turns on the size readings and I thought I'd pass it along.
Open a Finder window
Switch to List View
Click on the Gear icon
Click on Show View Options in the menu
Check the box titled, 'Calculate All Sizes'
Why this isn't on by default absolutely boggles the mind.
