Hi!

I'm by no means a nautilus guru, but I'll try to answer your questions
anyways :)

> 1.what is slow mime type, what is it used for?

No idea, but from what it sounds like it is the detection of the file *type*
by looking at the file *contents*.

> dummy child of a node?

This is so that the directory tree has expander arrows for the
subdirectories even though they are not loaded yet.

For example if you load your homedir, I bet there are subdirectories.
However, by default only your homedir is loaded and the dummy row is placed as a
child of every subdirectory node.
When you click the expander, it will read the directory, add the appropriate
nodes, and then remove the dummy node.

The basic cause is that: When there are no children of a node, no expander
arrow is shown. For partially loaded trees, this is undesireable since the
expander arrow must be visible even though the subnodes are not there yet...

Someone far more knowledgeable than me should do that, but I gave you a
rough outline for now ;)

Hope that helps...

cheers,
