dd Command PLEASE HELP!!!!

Hi

I am currently trying to create a image file to load on a CF Card using the dd command. but for some reason it firstly created a blank image file and now it is creating no image file.

What I am trying to do is the following: I downloaded a embcop file and then also three plugins to add to this program. I placed the files of the plugins under tools of the main file, embcop, as I would like to create one image file (now firstly I do not know if this is the correct place to put the plugins). Now I have saved the file on my Desktop, with the New Folder that I would like to place it in. I typed in the following:

sudo dd if=/home/anesh/Desktop/NacBox of=/home/anesh/Desktop/NACBox.gz

Now it reads it but this is the response I get:
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000435447 s, 0.0 kB/s

meaning that it is not detecting any files and not writing any records

Then after I created this image file I must now load it onto the CF Card.

Can any one please assist me with some advise as to how to get this thing working.

Thank you so much
