Not to worry. You can make the entire name show by changing the horizontal icon spacing in you Display Properties.

Just right-click on the desktop and choose Properties (or go through Control Panel, Display). When the Properties dialog box opens, click on the Appearance tab. Now click on the down arrow at the right of Item. When the list expands, select Icon Spacing (Horizontal). Use the spin box to experiment with the spacing, then click on Apply. Now go to the folder that contains your icon and press to refresh the window. Repeat until you find a spacing that works for you. Once you're satisfied, click OK to set your choices and close the Display Properties dialog.

You need to make some compromise on icon spacing. Increasing the spacing a little to allow longer names to display is OK. But if you increase the spacing too much, you may be unhappy with the extra desktop or window space required by your icons. The only alternative then, is to shorten the icon names.
