You can bulk-edit which app opens a file on OS X

Just fire up the Terminal and issue the following command:

$ open ~/Library/Preferences/com.apple.LaunchServices/com.apple.launchservices.secure.plist

You might need to reboot your Mac afterwards.

I needed this after deciding I no longer needed Keka to open every compressed file format known to man and got tired of seeing its file type icon on every .zip on my Mac.
