Managing Disk Space and Large Attachments

<h2>Problem</h2><p>Airmail's local data is taking up a lot of disk space (e.g. 35GB+), and the user wants to find and delete emails with large attachments.</p><h2>Solution</h2><p>Airmail does not currently support sorting emails by attachment size or displaying attachment sizes in the message list. To manage disk space:</p><ul><li><strong>Search for attachments</strong> – Use the search bar with keywords like <code>has:attachment</code> or file type filters (e.g. <code>.pdf</code>, <code>.zip</code>) to locate emails with attachments.</li><li><strong>Delete via Finder</strong> – Open an email with an attachment, right-click the attachment → <strong>Show in Finder</strong>, delete the file, and empty Trash.</li><li><strong>Use webmail</strong> – Log into your email provider's web interface (Gmail, Outlook, etc.) to sort by size and delete large emails from there.</li><li><strong>Do NOT use Clear Message Cache</strong> – This deletes locally stored emails entirely, not just indexes.</li></ul><p>For the backup folder location, go to Finder → Shift+Command+G → <code>~/Library/Group Containers/2E337YPCZY.airmail</code>.</p>
