To transfer a Gmail folder to another account, start by setting up both Gmail accounts to enable email forwarding. In the source account, go to Settings > Forwarding and POP/IMAP, and enable IMAP access. Then, in the destination account, add the source account as a POP3 account under Settings > Accounts and Import > Check mail from other accounts. Use the email client, such as Outlook or Thunderbird, to connect both accounts via IMAP, and then drag and drop the specific folder from the source account to the destination account. Alternatively, use Google Takeout to export the emails from the folder in the source account and then import them into the destination account using the "Import mail and contacts" feature.
