So, I just realized that there are nearly 100,000 emails in my "all mail" gmail box, mostly due to the amount of junk that comes into my junk box. I get a couple hundred junk a day. Apparently when I delete all those junk emails, they don't get deleted from "all mail." However, All mail also contains all the emails that I want to keep. If I just delete everything in All Mail, will it delete it all from everywhere? How do I get rid of just the 95,000 junk emails, without erasing the 5,000 good emails? Does the All Mail box affect the inbox and my other mailboxes?
