Ensure files on finder show the icon of the default app, not the old deleted app I deleted an app that used to be the default app for a file type, but its icon still remains in Finder windows:



How can I replace those icons for the icon of the current default app?

Things I have already tried:


Globally set the new app as default app for that type of file.
Manually removed things related to the old app (as per this tuto).
Relaunched Finder and rebooted system.


My OS version is 10.11.6 (15G31) (El Capitan).

Any help kindly appreciated!
I think you may need to rebuild the Launch Services Database.
The simplest, non-techy way would be to use Onyx (freeware)
