[ubuntu-uk] Icon-sized front pages of pdfs

[Rowan Berkeley]

Hi,

I have over a thousand pdf files, and I have noticed that every time I
open one of the sub-folders containing them, the file manager starts
whooshing around trying to collect tiny icon-sized copies of the front
pages of every pdf in the sub-folder and display them next to the file
details in the file list. There is a simple preferences box which allows
the usual modifications of what gets displayed in a file list, but I
can't see how to deactivate this particular feature. Does anyone know a
way?

best, R
