Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

You downloaded the file and saved it in /home/nrc3/Desktop. However when you became root you changed to the /root directory. This is done automatically when you change to root in some cases. This is why i had suggested the command 'pwd'. In your case you had 2 options to installing the flash 10 file.
1. You can change to the correct directory and install it
dpkg -i filename.deb
2. You could run the dpkg command with an absolute filename.
dpkg -i /home/nrc3/Desktop/filename.deb
It may be worth it to you to read up on the difference between relative and absolute file paths. It will help you understand how to navigate your system when in command line. In a nutshell an absolute file path is the location of a file starting from /. A Relative file location path is the location of a file starting from where ever you currently are. Once you learn the difference you will find yourself using it without even thinking about it. You will start running commands like "cd ../../Foldername/" or "cd /usr/share/".
Here is a tip to help you in the future. When you change from your normal user account to root, you can do it 2 ways. You can type 'su' and enter the root password. This will make you root without changing what directory you are in. The other way is to type 'su -l" and enter your root password. This will change you to root and move you to the /root/ directory.
To tell you the truth, I was never aware that "clicking on" a deb file was supposed to install it.
It's not. A .deb file is just a collection of files; much like a tar file. You'd need to setup gnome or kde to run something like "gksu dpkg -i $1.deb" before a GUI could automatically install it. Given that normal users aren't supposed to be installing packages (other than with sudo), as well as that you should normally use apt (apt-get, synaptic, etc) to install packages from a repository, there's little reason to setup the GUI to install a .deb.
Evo, worm, brian, Eric, quake! Thank you all! Thumbs-up all around! You all were right, but Worm's statement about shifting user-to-root was balls-to-the-walls dead on!
I am sure that I have seen somewhere, "download this .deb file and double-click, or you can dpkg from terminal..."
I thought the icon was to be used in the GUI, no? Why is it there if it really has no use????
Somebody mentioned Synaptics. I have seen that around... I think it belongs in this thread as a (part of a) solution. Please eleborate on what it is and how it is used, and if it is a file that I can download...
Now it's time to relax with a Dubian!

Did you start off with KDE, or start with Gnome and add KDE (like I did) when you installed Debian? Synaptic is a GUI package manager, you can browse all the available software and install from it. It comes as standard with Gnome, but if you've just got KDE I think you'll have to insall it using aptitude or apt-get in the terminal:
