7. Shapefiles VS Layers
A shapefile (.shp) is a vector data
storage format for storing the
location, shape, and attributes of
geographic features.
Stored in a set of related files and
contains one feature class.
A layer file (.lyr) is a file that stores
the path to a source dataset and
other layer properties, including
symbology.
Does not store the data's
attributes or geometry.
A layer file primarily stores the
symbology for a feature and other
layer properties related to what is
seen when the data is viewed in a
GIS application.
See :Layer Packages ; Hint: Right Click on a feature data
 If a layer file is sent to a user on another machine :
 Nothing displayed on the map because it does not contain the source
data.
 User must have the layer file and the shapefile it references.
