There are many ways to customize Finder to your liking. I happen to like the “View As Columns” setting, just because it’s quicker when going through folders in Finder. Many times when I have a file, the name is so long it gets cut off. Most users just drag the column width temporarily, so it fits. Oddly enough, the next time you open up Finder, the column width goes back to the default setting. To keep the Finder width from changing:
- Open Finder and make sure you’re in the Column View mode.
- Hold down the Option key while holding down the the 2 small vertical marks on the bottom of a column.
- The next time you open Finder in the Column View mode, the filenames should fit perfectly.
