Many PDF file names are not explicit, but their title is. I was looking for a mean to show PDF title in file explorer column (when using detailed view), I posted on stackexchange but did not found any solution
I was using Thunar, and I changed file explorer to thunar because some python bindings exists. It is Python nautilus project
Just install it, on arch it is
After, you have just to read
And check it works adding copying
column list nautilus preferences.
Now I was sure it was possible some custom columns in nautilus detailed view. It was time to show pdf title. I've tested different python packages to get pdf title :
python2-pdfrwpackage, it cannot decrypt
