Nautilus icon positions

I'm looking for where Nautilus stores the icon positions on a Ubuntu 10.10 system. I would like to back-up this information in case it's lost somehow, and possibl开发者_运维问答y programatically manipulate this information.

All information I've found seems to indicate that the information has been migrated to gvfs's metadata stores. Is there a way to query/modify this information, and where is it stored?

You can get the metadata stored with gvfs using gvf-info. Probably you might want to read some of the decisions taken in a blog post from Alexander Larsson: "Data about data".
