Thanks for the help.
I found out that 95% of the space are in https://www.pythonanywhere.com/user/(MY_USERNAME)/files/home/andersboje/web2py/applications/welcome/errors
And I am unale to upen the folder. It is loading for min. with out any luck.
I am unable to see what is in the folder or backup (zip) solution becuase they ain't any space left.
I think the Error folder contains rows/files like this:
