Show File & Folder information directly within the Finder & Desktop

You can set Mac OS X to automatically display file and folder information directly within the Finder and on the Desktop.

Enabling extra item information displays:
* Get to the Mac OS X Finder / Desktop
* Open the ‘View’ menu
* Scroll down to ‘Show View Options’ (or hit Command+J)
* Click the check boxes next to ‘Show item info’ and ‘Show item preview’

Extended item info and previews will now be included on items displayed in the Icon view.

Enabling this feature shows things like the item count of a Folder when in icon view. My personal favorite part of this ‘show item info’ feature is the ability for picture files to show their dimensions directly under the file name, this is so incredibly useful for anyone frequently working with images and manipulating pictures.
