Now for my second question of the day, I am using a small laptop, that due to the lack of size on the harddrive had to buy an 20GB external harddrive that plugs straight into the back of the machine. I installed JDK on there, but when I try to use DoS to complile my Java classes I can't seem to get to the folder where my code is keep. So I have to use the compile button on the IDE I'm using (which is JCreator Lite by the way). Now I have no problem using JCreator, but I'd like to able to use to DoS to compile my programs, but I can't access the folder I want. I put in cd E:\JavaCourse in the command prompt, but i keep getting a message telling me that folder cannot be found and I know it is there. Does anyone know why I can't do this? Stephen
