Set default pdf icon with Foxit Reader On macOs High Sierra I am trying to set a default icon for .pdf files: when I used Adobe Reader all the pdf files showed its icon, then I uninstalled it and replaced it with Foxit Reader as default app to open the same file. However all the pdf files now show a white icon and I would like them to show the Foxit logo instead.
I tried to copy-paste the logo from Foxit to a random pdf and it does work, but this cannot be applied to the whole configuration (this means that I should copy-paste everytime the logo in every single pdf file).
Is there a way to set the default icon?
Once you have changed the default application using Get Info, you may need to clear the icon cache.

To get started, close all open applications and then launch Terminal from Macintosh HD > Applications > Utilities. Copy and paste the following command at the Terminal prompt and press Return to execute it:

sudo find /private/var/folders/ -name 'com.apple.dock.iconcache' -delete
sudo find /private/var/folders/ -name 'com.apple.iconservices' -delete
sudo rm -r /Library/Caches/com.apple.iconservices.store


Restart, job done.
