问题
I have started to learn assembly language. The assembler I am using is NASM. Operating system is windows 7 32 bit on VMWARE. I am learning the language by watching video tutorials in which the instructor is using advance fullscreen debugger. The problem is I don't have the notes he provided to his students in which he gave instruction about how to use AFD. I can't understand the use of AFD. So I decided to go for Ollydebug.
My first assembly programming is a DOS application (COM) file. When I tried to open the COM file in Ollydebug, It says "unable to open the file". I am running Ollydebug as administrator. So can anyone solve eithet of the problem, so I can continue with the tutorial?
- Tutorial or some documentation on AFD(I googled but unable to find).
OR - Why I can't open the COM file in Ollydebug and a way to open it?

I am quite late to reply to this question but for future reference this link WeToLearn provides a comprehensive tutorials on debugging COM files with AFD . The Article name is "8086 Assembly Debugging with AFD - Advance Full Screen Debug [PART 1 - BASIC]" . He has explained some useful and basic instructions to start debugging on AFD .
Main keys I would like to mention are F1 ( Step Over ) , F2 ( Step In ) and F4 for help you can find about others on that link.
Look at these links Basic Debugging and Advance Debugging using AFD
