Ok Andrea, it's a little hard to explain the issue, but I understand what you explained.
I'll try to give you an example of my question.
I added a directory datastore that has the shapes: roads1, roads2 and roads3. Then I add all of them as a feature type. I add a new shape called roads4, and go to FeatureType and press the new button. In the list of available shapes, I have all shapes I already added, plus the new shape roads4. For a small number of shapes, it's not a problem, but when we have thousands of them, it's a waste of time, because we have to search the new shape added later. This is what I've tried to ask in the first email, but I didn't explain correctly.
By the way, we have found a problem with kml and styles, using and image like a texture. The GoogleEarth can't render the content of the polygon. If anyone already have the same problem, please help me. 
Thank for the reply Andrea.

Hello there,
We are adding data to geoserver using the Directory of spatial files
method, because we have a lot of shapes to include. But something we
have notice is that when we add a shape, he's still in the list of chose
for new shapes. We were wondering if this is expected or if there is a
way to disable this. If there is something expected, no problem, we only
want to know if there is a way to save work, because we waste time
searching the shape we haven't added yet.
I'm not sure I understand what you're saying.
The directory datastore should always provide an up to date list
of known feature types, so when you go into the "new feature type"
drop down you should see an updated version of the list of shapefiles
you have on disk. But the feature types should not be available
to the clients until you actually register them into the GeoServer
administration (so, there is no "auto add" of the shapefiles into
the published list).
Cheers
Andrea
