Thunderbird add-on for extracting attachments from e-mails

It does two things:

1. It saves attachments from selected messages to a folder of your choosing
2. [Optionally] deletes those attachments from messages

Who needs this?

If your mail server got clogged up and you want to make room but are unwilling to sacrifice your e-mails, Thunderbird allows you to save attachments as separate files and then "delete" them. This has to be done one-by-one. This add-on enables you to do it in bulk. I would be careful in selecting a lot of messages at once since you might run into resource availability issues (lack of RAM).

Does this delete attachments?

Only if you want it to. After saving you will be asked whether you want to delete those attachments from selected e-mails or not.
