Windows Reserved Filenames

A colleague asked me to help name a folder with a certain name and when I did the name refused to stay. I kept trying and was so confused/annoyed as to why I couldn't rename the folder with the given name. I found out later that the name I was using to name the folder is a MS DOS/Windows reserved name that can't be used to name any folder. After the cut is a list of reserved names for Windows
