How to delete all archived emails? I have many of them in the "All mail folder" but they are mixed with other e-mails.
In Gmail, there is no "archive" label.
All emails you sent to "Archive" - Actually removes any other label from it and can be found only later in the "All Mail" label.
But I found a way to find only the messages sent to the "archive".
Write in the search bar:
has:nouserlabels -in:Sent -in:Chat -in:Draft -in:Inbox
In the search results you will see all the messages which are not under any label, which is actually all the messages you have ever sent to "Archive".
You can now delete all search results...
