raster - Getting information out of an ArcGIS .lyr file

I'm using ArcGIS 10 and I downloaded a Raster layer from here: http://bioval.jrc.ec.europa.eu/products/glc2000/products.php

When I unzip it I get the following files:

• 1 Aux-File (15KB)


• 1 ArcGIS-Layer (14KB)


• 1 Tif Image (37MB)



• 1 .lyr file (XML Document) (6KB)


• 1 .tif file (XML Document) (15KB)


• 1 .tif.aux file (XML Document) (5KB)


• 1 .tif.ovr file (OVR File) (1.8MB)


• 1 .tif.vat file (DBF File) (2KB)

When I open the .lyr Layer in ArcGIS I get a nice colormap with a good legend (as can be seen in the Table of Contents). Looking at the Attribute Table I see only numbers, no description.

Where does the .lyr file gets its information from?! I need its information to create a legend and to know which number is what.
