ThunderPlunger is Thunderbird extension, it can remove orphaned files from removed email or news accounts. A few new ways to keep Thunderbird clean. This function will remove these files from your disk. Access this function from the context menu for any news account folder by selecting "Remove Orphaned Files". Once you restart Thunderbird, any such files will be removed for that account.

When you remove a POP3 email, RSS, or News account Thunderbird seems to leave many of the account's files lying around on disk. This may be to assist in a future "un-remove" or archival process. But the disk consumed by some accounts can become quite large and sometimes you really just want to permanently and completely remove an account. This function helps keep your computer clean by removing folders that are determined to be "orphaned" from any known current account. Select "Clean Accounts" from the menu available from ThunderPlunger's status bar icon. At the next Thunderbird restart, this add-on will check the following to identify probable "orphaned" folders for removal:
1. Thunderbirds default POP3 email storage location
2. Thunderbirds default NNTP (News) storage location
3. A historical log, established and maintained by this add-on, of past and current accounts

Please Note: it is possible to have more than one card in an address book for the same email address. So you may be prompted multiple times to approve card deletions within an address book. Responding to these confirmations with the Cancel button will prevent that card from being deleted and you will be given the opportunity to cancel the entire operation (with no items deleted) for the current address book.

Note that installation into Thunderbird is a little complex (this is due to Thunderbird's internal mechanism rather than because of any issue with the addon - these instructions would apply to ANY addon).

1. Click the Download Now area on the page linked below. You are prompted to save the addon's file onto your computer's hard disk. Place it in a location that you can remember. It need be stored there only temporarily.

2. Once the file has been downloaded and stored, select the Tools->Extensions menu item in Thunderbird. Then press the INSTALL button on the dialog that is displayed. An install dialog will be shown. Just press the INSTALL button and wait for the installtion to complete.

3. Once you have completed the install, there is no need to keep the xpi file downloaded in step 1 any longer. Feel free to delete it from your hard disk.
