disable thumbnails? Thunar did not work?

[gold_finger]

Not sure what might be wrong.  When I tested creating and modifying that file it worked to stop the creation of thumbnails.

Open a terminal and post back the output of this command so we can see what your tumbler config file looks like:

Code:

cat ~/.config/tumbler/tumbler.rc

One note:  when disabling thumbnails with that config file, I don't think that alone will delete any prior existing thumbnails.  You should manually delete them from the folder(s) they are in.  From that point forward, no more thumbnails should be produced.
