<p dir="auto">Hi Tobias</p>
<blockquote>
<p dir="auto">– The attachments are saved to the folder in the Library when you hit the "QuickLook" button in the message to display a attachment.<br>
– They are deleted again from this folder when you delete the message that contained the attachment.</p>
</blockquote>
<p dir="auto">From my understanding attachments are saved in the <code>Application Support</code> path when MailMate is somehow asked to deliver the attachments to an external service. This happens when:</p>
<ul>
<li><em>Viewing</em> the attachment via Quicklook</li>
<li><em>Opening</em> the attachment via the ‘Open with’ system of macOS.</li>
</ul>
<p dir="auto">In the latter case be aware that some tools which open your file will write new files in that location (think Archive Utility: If you open a zip file Archive Utility will create a folder with the zip content in MailMate’s Attachment folder. Be aware, if I understand this correctly this folder inside the attachment directory will never be deleted by MailMate.</p>
<blockquote>
<p dir="auto">Can it have any negative side effects if I deleted files from that folder manually?</p>
</blockquote>
<p dir="auto">I don’t think so. When you delete an attachment from that directory and quicklook th it again, MailMate will save it there again.</p>
<blockquote>
<p dir="auto">Moreover, since the attachments are stored in the message (.eml) file anyway, I don’t see why they should take up space on my disk another time, so from time to time I might remove them from the Library IF this doesn’t cause any trouble and of they aren’t purged from that folder automatically at some point anyway (i.e. even if I don’t delete the message itself).</p>
</blockquote>
<p dir="auto">This sort of clean-up is a great idea! (Thinking of creating a little <a href="https://www.noodlesoft.com/">Hazel</a> rule! :-) ) But I think the final word whether this is really save to do should have Benny here.</p>
<p dir="auto">Cheers,<br>
Leo</p>
