Hate how Mac OS Snow Leopard shrinks/hide long file names ? you can overwrite the settings so it doesn't limit to ~15 characters only.
Launch the Terminal and input the following:
[ Hide ] defaults write com.apple.Finder FXDesktopLayoutGridCharCount -int 255
osascript -e 'tell application "Finder" to quit'
You can change the 255 to any other reasonable number, this variable limits how many characters to be shown.
