Expand Finder Columns Quickly
Column view in the Finder is great for navigating through your disk's hierarchy, but the columns often aren't wide enough to show the full names of all the files. To expand a column to a width that will show all file names in their entirety, double-click the handle that you would normally drag to expand or shrink the column. To expand all the visible columns to that width, Option-double-click the handle.
