Sent folder is full, i have deleted the mesages and still get the same error, HOW DO I FIX THIS?

I have read mozillas help question and have not been able to fix my problem, I am having the same problem with the trash folder.

If you want to keep those messages but reduce the file size:
Archive your Sent folder.
How to set up Archive options - if not already set.
* https://support.mozilla.org/en-US/kb/archived-messages
Archive by month and year and choose to 'keep exisitng folder structure of archived messages'
Then select the 'Sent' folder to see emails.
click on first email to get focus.
Press 'Ctrl' key and 'A' key to select all emails.
They will be shown as 'conversations in the Message Pane'.
click on the 'Archive' button.
This should empty the Sent folder and place all sent emails in 'Archives' under the respective year, month and Sent folder.
