I ran this command in Terminal, which supposedly clears all duplicate applications from the "Open With…" menu and now many of my files are just showing up as blank images (.zip files, .dmg files, .rar, etc.) and they don't open with the correct application. I did log out and log back in after doing this. Help!!
