My Nautilus file-manager does not show a preview of PNG files.
Ubuntu Version: Ubuntu 18.04.2 LTS
Nautilus Version: GNOME nautilus 3.26.4
I have tried various "solutions" form the web like :
sudo chown -R $USER:$USER ~/.thumbnails
sudo chown -R $USER:$USER ~/cache/.thumbnails
sudo rm -rf ~/.thumbnails/* ~/.cache/thumbnails/*
After the last command I do not get any thumbnails for other files as JPG, BLEND, TIF and more.
I also looked at the Preferences from Nautilus which configure to only show files smaller than 4 GB. But all the files I'm concerned about are way smaller than 4 GB.
How can I configure Nautilus to show Thumbnails for all these file types?
