Dell sent me a "Drivers and Utilities" disk for this 17R 5721 laptop.  So far I have not been able to locate instructions.  Looking at the folders on the disk, there is a folder with the name ZIPFILES.  Just looking at the names of files in this folder causes the system to appear to run to extract them - - somewhere.  Since I have no instructions I don't know what this may be.  So I'm looking for information on this disk, to try to make the most of it. 

The PC is a Windows 7 64 Bit laptop, 17R 5721
