In Gmail, there is no distinct "Archive" folder. Instead, the archive is accessed through the "All Mail" folder. When an email is archived, Gmail removes the "Inbox" label from that email, so it no longer appears in your inbox but remains in the "All Mail" folder along with all other non-deleted emails. You can find the "All Mail" folder by clicking "More" on the left side of your Gmail interface and then selecting "All Mail." This is where all archived emails reside. You can also search within "All Mail" to find specific archived emails by excluding those still in the inbox with the search query NOT label:inbox.
