OT: set pcmanfm as default file manager in 11.10?

[Dave Hunt]

Hi,

Using 11.10 and the latest Orca from master, I find that opening a large 
(many folders and files) directory in Nautilus will cause the entire 
session to be unusable and unresponsive.  Opening this same directlry in 
pcmanfm is a nearly instantaneous operation.  When I open the gnome 
control center and to to the system info dialogue, on the listing of 
associated applications, I only see categories for web, music, video, 
and photos.  Posts in the Ubuntu forums suggest there should be more 
pages, including file manager.  I'd appreciate an accessible way to do 
this.



Thanks,


Dave
