Instantly Resize Finder Column View to Fit File Names in Mac OS X
Column View is one of the more useful file browsing view settings in the Mac OS X Finder, but it has a usability flaw that’s initially visible to most users; file names and folders often don’t fit, thus they wind up truncated and become unreadable.
Rather than dragging around every single column to accommodate the appropriate file size to make them readable, you can use a super-simple trick instead to instantly resize the columns to fit the names which are visible.
