Bulk deleting non-labeled e-mails through the gmail web interface is less than perfect.
Might there be some way to search for e-mails which are not in a specific folder? Gmail is rather unique in that everything is stored, sometimes multiple times. So that if an e-mail is stored only in all-mail then it could be marked for deletion. Theoretically.
In theory there is no difference between theory and practice; in practice there is.
