Question or Issue

I have been on the Basic package for many years. I do not want to close my account. I overfilled my account long before the current charging regime came in.
I cannot afford a paid account, so I need to move my files out and close the account, or at least keep it to 2GB. When I try to move the files out, I get a warning message saying I cannot move anything unless I purchase an account. I cannot afford an account.
I am sure there must be an easy way around this. However, finding out what that easy way is is extremely time consuming. Please can someone just tell me the easy way without me having to read hours worth of 'Terms & Conditions'.
Thank you.
