Full file name under desktop icon, not a finder window.

No. The room provided is limited. However, if you select the name it will display the full name for you.

the default maximum length of a file name that finder will show completely for desktop files is about 20 characters. anything longer is shortened. you can change the default maximum length to, say, 50 as follows

run the following terminal command (copy and paste please)

defaults write com.apple.finder FXDesktopLayoutGridCharCount -int 50; killall Finder

credit to biovizier for posting the command.

Try launching "/Applications" > "Utilities" > "Terminal.app" and entering these commands:<pre>
defaults write com.apple.finder FXDesktopLayoutGridCharCount -int 50
osascript -e 'tell application "Finder" to quit'</pre>

Then restart the "Finder" by clicking on its "Dock" icon.

You can try different numbers other than "50" until you find a value that suits your preferences.

Edit: oops, too slow I guess.

It's 32 characters until you select the filename and then it will display up to the 255 character limit.
