[Gvsig_english] copying shape file layers

[Benjamin Ducke]

Hi Klaus,

In GIS (not only gvSIG but any GIS) terms, a layer
is just a link (reference) to the actual data source 
(such as a Shapefile), not the data itself. So if you 
use gvSIG's "Copy" function to copy a layer, then you
only duplicate the link to the same file on your
disk. If you want to actually duplicate the
Shapefile data, then you have to use your system's
file manager to do so.

Best,

Ben
