Concerned about space in my Gmail I just took a rash and stupid action, and "deleted" everything from the "archive." I did this on Mozilla Thunderbird on my mac. It's clear to me I haven't lost the messages (They're now in my Gmail trash, plus I have a second laptop that until it syncs has everything where it belongs, and time machine backups from a couple weeks ago....), but I am unsure how to restore the messages (i.e. get them all back in their appropriate folders). I would be happy with either
the best way to restore my Gmail based on the version sitting on Thunderbird on another computer or Time Machine backup
the best way to reverse this mass "deletion"
Do you have suggestions?
