When an attachment is opened, the file is stored in a temporary folder under the email account’s inbox, in a convoluted naming scheme that references the attachment to the email. Although these files are supposed to be temporary, they stay behind on the drive and can occupy gigabytes of space. Given the complex folder structure used by the Mail app, there’s no easy way to navigate through all these folders and delete the attachments that are left behind.
Any ideas of how they can be deleted? Do any apps exist that can do this automatically for the user?
I suppose that as long as one uses an IMAP acct,, the email accounts could be removed from the system and their respective mBoxes deleted in their entirety, before adding the accounts again on the computer. But I’m not clear what else could be lost following this drastic method, which would also be time consuming in case multiple email accounts are used on the same computer.
Any suggestions would be appreciated.
