I have approx 3000 emails in my Gmail that I am wanting to purge. All of the important emails I have put into folders with labels.
I of course do not want to delete these important emails, so deleting all emails without labels is my desired outcome.
All of which suggest disabling conversation view and using the search term
has:nouserlabels. However this returned about 50 emails that have since been deleted, but now no longer returns any search results.
I have folders with subfolders and sub-subfolders, so I also attempted to get around this by usign
!in:parentFolderName but this did not work to not include subfolders...
Can anybody help?
