If you are using Finder in column view, it can be very frustrating when viewing file names that are longer than the column width, usually around 24 characters. But luckily, there is simple solution for this – you can click the vertical column divider and move it until file name becomes completely visible.
Even better, you can double-click on it and the column will stretch just enough to display the longest file name in its full length.
In this case the folder name User Guides And Information was a little too long, but once double-clicked, the column stretches nicely to display the folder name in full.
Nice little tip.
You can also hold the alt/option key when you mouseover the filename to have the full-name popup instantly.
