BleepingComputer.com: Command Prompt Copy Question

Usings Windows XP Media Center Edition SP2

I thought I understood how to do this, but I am obviously missing something. I am wanting to copy a file called TODO.txt from the following directory:
C:\Documents and Settings\Owner\Desktop

To the following Directory:
C:\Documents and Settings\

So I used the following command to go to the correct directory:
cd C:\Documents and Settings\Owner\Desktop

I use DIR to varify that the file is the directory I am in. Then I use the following command to make the copy:
Copy TODO.txt C:\Documents and Settings\

But, it seems the syntax is incorrect for that. I was,however, able to successfully copy the file to C:\ using "Copy TODO.txt C:\"

Anyhow, I could go through the various commands I have tried, so I figured I would try the following:
Copy C:\Documents and Settings\Owner\Desktop\TODO.txt C:\Documents and Settings\TODO.txt

I get "The system cannot find the file specified"

So, I am at a loss. Everything I read tells me to essentially do the following:
Copy Source File Destination File

Thanks for reading through all that and for any help. Also, I apologize if this is in the wrong place, which it appears it might be.

It appears my problem was simply not putting quotes around where I wanted the file copied to...I don't think I saw that in any guide I saw.

Yup, when you reference a path that contains spaces you need to put quotes around it. Otherwise the command will the see the words after a space as arguments.
