Column View in the OS X Yosemite Finder - dummies

Column View in the OS X Yosemite Finder

By Bob LeVitus

Column view is a darn handy way to quickly look through a lot of folders at once, and it’s especially useful when those folders are filled with graphics files. The Column view is a great way to display windows in the Finder.


To display a window in Column view click the Column view button on the toolbar, choose View→As Columns from the Finder’s menu bar, or press Command+3.


Here’s how you can click around in Column view to see the list of folders and files:

  1. When you click the Documents icon in the Sidebar, its contents appear in the column to the right.

  2. When you click the Templates folder in this column, its contents appear in the second column.

  3. When you click the biz cards BL.TV show 12 folder in the second column, its contents appear in the third column.

  4. Finally, when you click the BLTV Logo icon in the third column, the contents of that file appear, along with some information about it: It’s 511K in size, was created on June 9, 2014, and so on. That’s called the Preview column.

When you’re poking around your Mac in Column view, the following tips are good to know:

  • You can have as many columns in a Column view window as your screen can handle. Just drag any edge or corner of the window to enlarge it so new columns have room to open. You can also click the green Zoom (Maximize) button to make the window fill the screen.

  • (Hint: To get out of full-screen mode, press Esc or move your cursor to the top of the screen and click the green Zoom button that appears near the top-left corner.)

    If you Option-click the green Zoom button, the window will expand to “just big enough” to display all columns with content in them.

  • You can use the little grabber handles at the bottom of every column to resize the column widths.

    To be specific:

    • If you drag a handle left or right, the column to its left resizes.

    • If you hold down the Option key when you drag, all columns resize at the same time.

    • If you double-click one of these little handles, the column to its left expands to the Right Size, which is the width of the widest item in the column.

    • Right- or Control-click any grabber handle for a pop-up menu with three options: Right Size This Column, Right Size All Columns Individually, and Right Size All Columns Equally.

  • The preview column displays information about the highlighted item to its left, but only if that item isn’t a folder or disk. Why? Well, if it were a folder or disk, its contents would be in this column.

    For many items, the picture you see in the preview column is an enlarged view of the file’s icon. You only see a preview when the selected item is an image file saved in a format that Quick Look can interpret (which is to say, most image file formats, including TIFF, JPEG, PNG, GIF, and PDF to name a few, as well as many other file formats, including Microsoft Word and Pages).

    If you don’t like having the preview displayed, you can choose View→Show View Options and disable the check box for Show Preview Column.
