Stuck on Level 1 mission 4

[GennyBoo]

Hello, this game looks fun, but if I'm stuck here, I don't know what I'll do when I get to tougher missions! :S

I am stuck on mission 4

I created the folder (my folder) and the * appeared next to mission 4. But when I type smission 5, it says that there is a current mission.
I tried typing cd myfolder (as suggested in another post), it takes me inside myfolder, but then I'm stuck.
I tried typing rmission but it does not work.
I tried changing dir but it doesn't work

I am not sure what I am doing wrong... Help please?

Thank you
