As the title says, how do I remove Templates and Archive folders? [https://support.mozilla.org/en-US/questions/1451068#answer-1671364 This post] does not have an answer, and [https://addons.thunderbird.net/en-US/thunderbird/addon/hide-email-folders/ this extension] does not work. I have tried deleting the files from the folder and restarting, but they just get recreated: C:\Users\User\AppData\Roaming\Thunderbird\Profiles\profile\Mail\smart mailboxes I have unsubscribed from the Archive folder in my accounts settings and deleted them from my mail server. Templates does not even exist on my mail server. See attached picture, but these are annoying as I don't use them and they just take up space and are distracting. Any ideas?
