<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>You can create a feature class in a PGDB with
the same type of features and projection as the shapefile, but using a new extent
(Xmin, Ymin, Xmax, Ymax). You need to select the new extent in a way that
will ensure the existing shapefile will fit into the center area of the new extent
while leaving enough space (spatial extents) for new features to expand in all four
directions. Then you can import the features in the existing shapefile to
the new feature class or copy the features and paste them to the new feature
class. This is probably the simplest, yet sure way to solve the
problem. Copying projection file around may or may not work depending on
the relative extents of the shapefile to be copied. </span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Also keep in mind that extending/expanding
feature layer extent is normally done at the expense of loss positional
accuracy because there is a limit on the number of coordinate units in PGDB/SDE.
Normally, this limit is not a concern as long as you are not dealing with
nation-wide data layers.</span></font></p>
