MainMenu Pro Icon

Rebuild Launch Services

Launch Services associates documents (such as text documents, zip files, music files and so on) with applications (such as TextEdit and iTunes).

Sometimes a corrupt file may cause the following problems: a) Finder opens your file with the wrong application when you double-click on it, b) your files and folders show the wrong icon, c) you see the same application more than once in the Open With menu, and d) you get an error code -10660 in Finder

If you experience any of these problems, try to rebuild Launch Services.
