Using ArcCatalog

Not all raster datasets have file
extensions, and some are stored
as folders. Because identifying
such raster datasets takes more
time, ArcCatalog skips those
without extensions by default
when searching through a
folder’s contents. Therefore,
they won’t appear in the
Catalog. The exception is the
ESRI grid format, which is quick
to search for even without a
filename extension. By default,
the Catalog will always search
for grids. If you choose to
search all files and display all
raster datasets, the contents list
will be slower to appear, but
you will see an accurate listing
of all raster datasets in all
folders.
Changing which files
appear as raster datasets
1. Click the Tools menu and
click Options.
2. Click the Raster tab.
3. Click the General tab.
4. Click File Formats.
5. Scroll down until you see the
appropriate raster format in
the list.
6. Click in the File Extensions
column to the right of the
raster format’s name.
7. Move the cursor to the end of
the selected file extension.
8. Type a semicolon (;), then
type an asterisk (*) and
period (.) followed by the
letters of the file extension.
For example, if you add the
file extension *.wbp into the
File Extensions column to the
right of Windows Bitmap,
both .bmp and .wbp files will
be recognized as Windows
Bitmap images in
ArcCatalog.
9. Press Return.
10. Click OK, click OK. 8
