  • I think what you are asking is how to turn off thumbnailing, perhaps because it slows the computer down too much? Unfortunately there isn't and option to do this at moment from within Files. There may be a way of disabling the thumbnailer (Tumbler) at system level but that would affect all applicaitons. Commented Aug 1, 2016 at 18:36
  • After a little Googling I found this link askubuntu.com/questions/232347/…. If you do not mind messing about with configuration files you can disable any (or all) thumbnailers at a system level using the method described at this link. Commented Aug 1, 2016 at 18:45
  • An easier way is to use dconf to edit the setting org.gnome.desktop.thumbnailers.disable to disable thumbailing of certain mime-types or org.gnome.desktop.thumbnailers.disable-all to prevent thumbnailing altogether. Commented Aug 1, 2016 at 18:48

tumbler is managing which thumbnails are generated in elementary OS .
In order to customize the tumbler config file, you can make a local copy by creating a tumbler folder in ~/.config and then copying the original config file tumbler.rc from /etc/xdg/tumbler to that folder.

The easiest way to do it, is to use these commands:

mkdir -p ~/.config/tumbler
cp /etc/xdg/tumbler/tumbler.rc ~/.config/tumbler/

Now, edit the file with your text editor

scratch-text-editor ~/.config/tumbler/tumbler.rc

search for the section

# PDF/PS thumbnailer

and change Disabled=false to Disabled=true. The changes should take effect after a relogin or restart.
